1 Overview of the YLR-Series Fiber Lasers

Introduction

The IPG Photonics YLR-Series fiber lasers are developed to meet industrial market demands of efficient reliable maintenance-free high power lasers. 

These lasers are a diode-pumped Ytterbium fiber laser with output powers ranging from 1W to 1.5 kW operating at the wavelength region of 1060-1100 nm.

The YLR-Series fiber lasers can be air or water-cooled. The wall plug efficiency for a fiber laser is typically exceeds 30 percent. 

All YLR-Series fiber lasers are Class 4 laser products and are designed and tested with important safety features. 

Follow this guide and apply laser safety practices for a safe and reliable device.

Laser light exhibits unique characteristics that pose safety hazards that are not normally associated with other light sources. 

Therefore, all operators and other people near the laser must be aware of these special hazards.

Audience

The audience for this guide are system integrators and technicians responsible for installing and operating the IPG YLR-Series fiber lasers in industrial and non- industrial installations.

Safety Information and Conventions

To ensure the safe operation and optimal performance of the product, follow all warnings in this guide. Safety precautions must be observed during all phases of operation, maintenance, and service.

Operators must adhere to these recommendations and to apply sound laser safetypractices at all times. Never open the chassis. 

There are no user serviceable parts,equipment or assemblies associated with this product. All internal service andmaintenance should only be performed by qualified IPG personnel.

Functional Safety:

The following safety functions are implemented to fulfill the requirements of EN ISO 13849-1:2008 + A1:2009 Cat.3 / PL d and Category 3 (Cat. 3). 

The safety functions are implemented exclusively in hardware:

  • Stop initiated by a safeguard:The safety electronics of the laser monitors the feed fiber cable (optical fiber interlock). If the laser is emitting and the feed fiber is disconnected from a mating device or broken, the safety-related outputs become de-energized.
  • Stop initiated by a safeguard:The safety electronics of the laser monitors E-Stop input. If the laser is emitting and the E-Stop is activated, the safety-related outputs become de-energized.
  • Safe start/restart button:The safety electronics of the laser monitors safety-related outputs. A fault in the safety-related outputs is detected before the next demand upon the safety-related output.
  • Dischargeof stored energy:The safety electronics of the laser monitors safety-related inputs. If the laser is emitting and a stop is initiated by a safeguard, the stored energy for the laser is discharged.
  • Prevention of unexpected startup:The safety electronics of the laser monitors safety-related inputs. Start of restart cannot occur after activation of a safeguard until safeguard is re-established and separate deliberate action occurs.

 

Class A Digital Device

This equipment is tested and complies with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. 

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this guide, can cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the users are required to correct the interference at their own expense.

Electromagnetic Compatibility

Compliance of the YLR-Series lasers with the EMC requirements is certified by theCE mark if identified by the CE label (Figure 1-1 on page 1-7).

General Safety Instructions

WARNING: You must exercise caution to avoid and minimize specular reflections as these reflections occur at the laser's wavelength and are invisible.
Specular Reflections

Often there can be numerous secondary laser beams produced at various angles nearthe laser aperture. 

These beams are called “Specular Reflections” and are produced when the laser light reflects off a surface where the primary beam is incident.

Although these secondary beams might be less powerful than the total power emitted from the laser, the intensity might be great enough to cause damage to the eyes and skin as well as materials surrounding the laser.

Equipment and Solvents
Light-sensitive elements in equipment, such as video cameras, photomultipliers and photodiodes can also be damaged from exposure to the laser light.

WARNING: The laser light is strong enough to cut or weld metal, burn skin, clothing, and paint. 

In addition, this light can ignite volatile substances such as alcohol, gasoline, ether, and other solvents. 

Exposure to solvents or other flammable materials and gases must be avoided and must be relocated away from this device.

Using the YLR-Series
CAUTION: Refer to the SPECIFICATION YTTERBIUM FIBER LASER document included with this product for proper electrical power requirements.
Before switching the power on, ensure that the incoming AC voltage is equal to the level noted in the specification.
Operate only in an environment with sufficient airflow capacity that allows for the specified heat load developed during operation.
Connecting Electrical Power

Refer to the SPECIFICATION YTTERBIUM FIBER LASER document included with this product to determine your models power requirements.

A power cord is not provided with the laser.

To connect the electrical power:

  1. Wire the power input terminal block on the rear panel of the laser to the voltage, phase and frequency indicated on the SPECIFICATION YTTERBIUM FIBER LASER document for your particular model.

L2 = Line Voltage, PE = Protective Earth, L1 = Line Voltage

  1. Cover the input power terminal block with the supplied cover.
  2. Secure the cable with the supplied strain relief.

 The electrical connection to the unit must be permanently connected to dedicated AC mains with a circuit breaker that does not exceed 20 Amps. 

This must be in close proximity to the unit and within easy reach of the operator and marked as the disconnecting device for the unit.

  1. Follow all national and local requirements when wiring to the unit.
Interface Wire Specification

The minimum wire gage is 18AWG at 15 meters (30 meters maximum regardless of gauge).The gage of the wire must increase as the  distance increases. For connectivity, the wiring and/or cabling must have an overall shield to ensure  proper functionality.The shield is to cover over all conductors and terminate at the unit where the conductors enter/exit the unit.

Connections to External Circuits

Except for Mains connection, the external connections between this product and otherexternal devices  are PELV (Protected Extra Low Voltage) as defined by IEC 61140.Non-Mains outputs of other devices connected to this product should also be PELVor SELV (Safety Extra Low Voltage).

Interlock Safety Circuit

YLR lasers include an Interlock Safety Circuit that uses a dual-channel system with monitored output and manual reset.

When you open the Interlock, the safety circuit opens and power to the laser diodes is removed.

Follow these steps:

  1. Closethe dual channel interlock (on 24-pin connector: pin1 is connected with pin4 and pin2 is connected with pin3). Otherwise, the internal main power supply is switched off and the emission cannot be turned on.

Once any of the pairs of the mentioned above contacts is opened, you cannot switch the lasers power supply on until the second pair is opened and then both pairs are closed.

  1. If you close the interlock (the Emergency Stop button is also released) and a fault is not detected, press the Start button to connect the remote start contacts, which enables the main power supply. The Power Supply (PS) Active signal enters a high state and power is supplied to the laser module.  The laser diodes remain inactive until a separate Laser Enable signal transitions high and an output power level set to a non-zero value.

The power to the laser diodes also turns on. However, under normal conditions the diodes only turn on after emission is enabled.

When you open the interlock or a fault is detected, the laser diodes are discon- nected from the main power supply. The Power Supply Active signal enters a low state.

A detected fault is latched and circuits open the monitored manual reset loop, thus preventing the laser from being restarted until the fault is addressed. If a fault is detected, such as a shorted interlock channel, or a shorted Start button, the safety circuit does not reset until the fault is corrected.

 If the remote Start button is shorted (this is the equivalent of holding in the Startbutton), the circuit does not reset when the interlocks are closed until the  safety circuit processes both channels open and then closed or the power to the safetycircuit is cycled (with the Start button in the opened state in both cases).

Initial Power-Up Sequence

CAUTION:All electrical connections (and water connections for Water-Cooledmodels) must be connected prior to applying power to the unit.

In addition and where applicable, all connections must be secured with screws to ensure proper functionality.

To initially power-up the system:
1. Ensure the E-Stop button on the front panel is pushed in.
2. Inspect the optical output end face to check for dust and debris (refer to “Optical Fiber Connector Inspection and Cleaning” on page C-1 for more information).
3. Properly align the output fiber into the delivery optics.
4. Properly secure optical output collimator.

WARNING: Never look directly into a live fiber and ensure that you wear appropriate laser safety eyewear at all times while operating the product. 

Ensure all power is removed from the laser when handling the delivery cable.

  1. Ensure the Interlock (pins 1to 4, 2 to 3) on the interface connector is closed.
  2. Release (pull out) the E-Stop button on the front panel and ensure that the external E-Stop (from the 24-pin connector) is disengaged if used.
  3. Ensure that the air-cooling vents are unobstructed to allow proper cooling of the device.
  4. Verify that the external cooling unit is powered on (for Water-Cooled models only).
Key Control

You cannot turn on or operate the device until the key switch is in the ON or REMposition. ON or REM is only applicable to products with the Local Control option.Products that do not have this option need to close the remote key circuit, pins 8 and 9 on remote connector (refer to Table 2-6 on page 2-19).

You cannot switch between ON and REM without moving position into OFF and then waiting a few seconds.

Rear Panel: 7-pin and 24-pin Connectors

There are two connectors on the rear panel of chassis: 7-pin and 24-pin. Figure 2-13 on page 2-27 shows the connections to 24-pin connector. 

Figure 2-14 on page 2-28 shows the connections to the 8-pin connector.

The two Interlock contacts ILK1 and ILK2 are connected between pins 1-4 and 2-3.

The Keyswitch is connected between pins 8 and 9. This switch should be closed to power system up in Remote Control Mode. 

The Start button is connected between pins 10 and 11. When closed it starts system in Remote Control Mode.

There is an isolated RS-232 interface (signals on pins 5 and 6 are referenced to return on pin 7). Two isolated analog signals on pins 12 and 13 are referenced to analog return on pin 14. Two differential modulation signals on pins 15 and 16 are also isolated. The control and diagnostic signals on pins 17-19 and pins 21-24 are referenced to return on pin 20 and are isolated.

Two contacts of the E-Stop button are connected between pins 1-4 and 2-3. When you push the E-Stop button, these contacts become open. 

They return to closed state when E-Stop button is released.

One isolated Power Supply Active signal on pins 5 is referenced to the return onpin 7.

Operation Control Modes

There are two control modes for the laser: Local and Remote. You select these modesusing the Keyswitch on the front panel (see Figure 2-2 on page 2-3).

If the Keyswitch is in the ON position, the Local control mode is activated. If the Keyswitch is in REM position, the Remote control mode is activated.

Table 2-9 details the differences between these two modes:

To turn on the device in Remote Control Mode:

  1. Turn the front panel Keyswitch counterclockwise to the REM position.
  2. Close contact pins eight and nine to provide the remote keyswitch function.
  3. Make momentary closure of pins 10 and 11 to activate the main power supply.
  4. Turn the emission on. Refer to “Local and Remote Control Modes” on page 2-29.
  5. Wait until the laser becomes active.

The laser is now ready for operation. You can now select a proper operation mode.

Selecting Operation Modes

In both control modes (Local and Remote), there are two main modes of laser emission:

  • Continuous (CW)
  • Pulsed (QCW)

Pulse Mode (QCW)

Pulse Mode (for QCW models only, Pulse-mode enabled) laser internally generates a sequence of pulses. Pulse duration and pulse repetition rate can be configured by:

  • Sending corresponding commands via RS-232 interface, or•Using the Pulse Settings submenu on the touchscreen display

The main difference between Pulse and CW modes is that in Pulse Mode the maximum peak power is considerably higher than in CW.

 However, the maximum pulse duration and the maximum duty cycle are limited to certain values  (refer to the SPECIFICATION YTTERBIUM FIBER LASER documentand refer to Figure 2-15). 

When in CW mode, the maximum pulse duration and duty cycle are not applicable.

Operational Sub-Modes

For each mode of laser emission (Continuous or Pulse), there are four operational sub-modes:

  • Standalone
  • Modulation
  • Gate
  • External (Analog) Power Control

The main difference between sub-modes of operation is how the laser power is set and the laser emission is switched on/off.

Continuous Mode (Pulse mode is disabled) laser generates CW emission (except forGate mode).

Standalone Mode (Modulation and Gate control disabled)

The value of pump LD current (controls output power) is controlled by:

  • Sending a RS-232 command, or
  • Sending an Ethernet command, or
  • Using control buttons on the touch-screen (in Local Mode).

 

Modulation Mode
  • The value of pump LD current is controlled as in the Standalone Mode.
  • Laseremission is turned on/off by the user-generated “Modulation” signal applied to pins 15-16 of External Interface Connector.

 

Gate Mode
  • The value of pump LD current is controlled as in the Standalone Mode.
  • Laser emission is controlled both, externally and internally .The user-generated “Gate” signal applied to pins 15-16 of External Interface Connector starts and stops internal generation of pulses.

External (Analog) Power Control

  • Thevalue of pump LD current value is controlled by the voltage applied between pins 12 and 14 of the External Interface Connector (see Table 2-5 on page 2-14 for more information).
  • Pulse sequence generation, modulation and gating are performed as in corresponding modes above.
Pulse Shaper Program (Optional Feature)
  • You can create and store arbitrary waveform pulses in the Pulse Profiles library.
  • You can create and store Pulse sequences (combinations of pulse profiles, delays, and repeats) in the Pulse Sequences library.
  • Pulsescan be started by Emission On command/signal (when Gate Mode is disabled) or by the “Gate” signal applied to Pins 15-16 of External Interface Connector (when Gate Mode is enabled).
  • You cannot select Waveform Mode if either External (Analog) Control or Modulation Mode is enabled.

See “Pulse Shaping” on page 4-1 for details on using the Pulse Shaper program.

Using the Touch-Screen Display

You can use the touch-screen display on the front panel for manual control of the device. 

You can view information about the device’s state and settings. In addition,activating certain commands from the main window invokes additional submenu windows. In Remote Mode, the touch-screen display function is disabled and canonly be used for display purposes.

Pulse Shaping

Overview

The Pulse Shaper program lets you sketch pulse points. It automatically fills in pulse (power level) lines, and computes all the emission pulse characteristics simultaneously. It also performs auto-correction in case constraints are violated.

A laser emission pulse is a custom time-based emission power signal, constrained by an output sample time, maximum power, maximum energy and minimum current (power) threshold, all of which are pre-configured in the laser.

Pulses are not zeroed visually when they go under the power threshold, although that is not reflected in the pulse energy calculation.

To avoid pulse energy limits, either shorten your pulse widths or reduce the value of the Time Scale.

Each time you change a Pulse Shape profile, the pulse widths are updated to reflect the current sketched pulse. You cannot exceed the limits established in the laser configuration.

You can create effective Pulse Shapes to meet the changing requirements of your applications. You can store Pulse Shapes in a Pulse Profiles library on the laser or locally to your computer. You can also create and store Pulse Sequences (combinations of pulse profiles, delays, and repeats) in a Pulse Sequences library or locally to your computer.

Shifting a Pulse Shape

You can manipulate an existing Pulse Shape to create new variations. This method can save you time and achieve better symmetry. See Figure 4-21 for an illustration of Shift Panel controls.

To shift a pulse:

  1. Select Newfrom the Shape menu.
  2. Create apreliminary pulse (preferably an alternating one) such as a square or sine wave.
  3. Set an emission step percentage value in the Shift Panel.
  4. In the Shift Panel, click Emission Shift Down (Eu∧) or Emission Shift Up (∨ Ed) to introduce an emission offset to the pulse.
  5. Set acertain Time Step value in the Shift Panel.
  6. ClickTime Shift Left (Tr>) Time Shift Right (<TI) to introduce a time offset to the pulse.
  1. Setan Emission Scale Ref percentage value. It should be the effective zero point of your pulse to get the best result.

 For example, if you are modulating a sine wave, set to be in the center point.Also, set an Emission Scale percentage value then click Expand Emission or Compress Emission to scale effective emission with respect to the reference point.

  1. Use the Time scaling slider to set a Time scale value. It should be the effective zero point of your pulse to get the best result.

Because of the sample time constraint, scaling can be unsymmetrical, and there could be a small range of ineffective scaling factors, all that is due to sample approximation during the calculations. 

IPG recommends you save the original pulse prior to modulating a pulse.

Serviceable Items

The unit should never be operated with any of the covers removed, including the front panel fan covers.

The input voltage to the laser is potentially lethal. All electrical cables and connections should be  treated as if it were a harmful level. All parts of the electrical cable, connector or device housing should be considered dangerous.

This device is classified as a high power Class 4 laser instrument under 21 CFR 1040.10. This product emits invisible laser radiation at or around a wavelength of 1070 nm, and the total light power radiated from the optical output is greater than 20 to 1500 W (depending on model) per optical output port.

This level of light can cause damage to the eye and skin. Despite the radiation being invisible, the beam may cause irreversible damage to the cornea. 

Laser safety eyewear is not provided with this instrument, but must be worn at all times while the laser is operational.

Service personnel should always follow correct Lockout/Tagout procedures per yourcompany’s policy to ensure all potential energy is removed from the system beforeservicing.

Optical Fiber Connector Inspection and Cleaning

Overview

You should regularly check the fiber connector for dust, dirt, or damage before youconnect to any external optic. The use of a dirty, or improperly cleaned, fiberconnector can lead to serious damage to the laser (Figure C-6 on page C-7 illustratespossible fiber failures).

 IPG Photonics is not responsible for any damages due to contaminated connectors.Tampering with the fiber connectors without training by IPG voids the warranty.

For cleaning a fiber connector, you need the following materials:

  • Powder free rubber gloves or finger cots
  • Lint free optical cleaning wipes and/or swabs
  • Acetone (optical grade, water free)
  • Compressed air (oil free, water free)
  • Microscope (IPG model or equivalent)
  • Light Source

You need to wear powder free rubber gloves during this cleaning procedure. Damage to the fiber connector can occur due to mishandling. The use of incorrect cleaning procedures or chemicals for cleaning is not covered by the warranty.

Acetone should be handled and stored in accordance to any local regulations (e.g. OSHA Regulation 29 CFR 1910.1200). Refer to each solvent’s MSDS (Material Safety Data Sheet) for additional information.

To clean the fiber connector:

  1. Switch off the laser main power by pressing the Emergency Stop button on the front of the unit and turning the Keyswitch to the center position.
  2. Leave protective cap on and clean the fiber connector exterior with opticalcleaner, wipe it with a clean optical wipe and dry with compressed air.
  3. Place fiber connector in the holder of the microscope.
  4. Place pressure on the center of the securing arm before tightening the locking screw as shown in Figure C-2.
  1. Remove cap and sleeve from connector as shown in Figure C-3.

Place the cap face down on a clean surface. Placing the cap face down on a lint free wipe is the best  choice if the surfaces are questionable.

  1. Focus the microscope onto the connector surface.
  2. Use light source to illuminate the face of the connector so that the light is reflected from the surface of the microscope. This is achieved if you see a bright golden shine from the IPG (yellow cable) connector end-face or a blue surface for the connector (see Figure C-6 on page C-7).

Always look at the surface at a slight angle to improve visibility.

  1. Inspect the surface carefully.Any contamination might lead to dark spots on the surface and eventual fiber failure (see Figure C-6 on page C-7 for examples). Ifcontaminationisvisible on the quartz block,continue to the next step.Proceed to Step 14 if there is no contamination visible.
  2. Try to blow away the dust with compressed air from the side.

Never blow air directly at the surface because you could embed contaminants into the surface. 

Always blow across the surface.

  1. While wearing powder free gloves, fold the lint free optical wipe into halves until it is roughly 1 X 1 ½” rectangle (see Figure C-4 on page C-5). Put a few drops of optical cleaner onto the lint free optical cleaning wipe on the folded edge of the wipe as indicated.

Do not ever reuse a lint free optical wipe or swab to clean the end face.

  1. Re-inspect the lens.
  2. Repeat step 10 withAcetone if lens is still contaminated.
  3. Ifnecessary, put a drop of Acetone onto a cleaning swab and gently wipe away contamination in a circular motion being careful not to scratch the lens. Then repeat from step 10.

Do not touch the tip of the cleaning swab with your fingers and use each swab onlyonce to prevent contamination.

  1. Repeat above cleaning steps until all contamination is removed. This cleaning procedure can be stopped at any time if a good result has already been achieved.

After fiber connector is clean use compressed air to clean the protective sleeve and install onto the connector.

Damage to the fiber connector can occur due to mishandling, the use of incorrect cleaning procedures, or chemicals for cleaning. This is not covered by the warranty.

  1. If the fiber is not to be connected immediately with asuitable optical component, use compressed air to clean the protection cap and install over the fiber end.

Make sure you clean the cap and sleeve before installing them back onto connector.

  1. Remove the plastic protection cap at the bayonet enclosure.
  2. For connecting the fiber to the bayonet, the red dot at the fiber has to be in line with the red dot at the bayonet enclosure.
  3. Gently slide the fiber all the way into the fiber port.
  4. Lock the fiber into place by rotating the bayonet knurled ring.

Hand tighten only as the use of tools can lead to damage to the bayonet enclosure.
