PREFACE

Thank you for purchasing the NuQ™ fiber laser. The NuQ laser is a pulsed fiber marking laser nominally delivering 1 mJ pulse energy with a fast turn-on time (125 µs) and high peak power (up to 10 kW) over a wide range of repetition rates (variable from 20–100 kHz), which maximizes production throughput and marking capability. With its near single-mode beam quality, the NuQ laser can produce ultra-fine, crisp marks every time. The system design ensures zero bleed-through power when the gate signal is off, to prevent the appearance of ghost lines between marks, even on very sensitive materials. Complete with industry standard interfaces, the system is pumped by single-emitter diode lasers, which offer long lifetime and maintenance free operation.

Pin 9: StrobeOnce the laser power bits have been sent, it is necessary to latch the signal for the laser power to be set. A TTL high signal must be sent to do this, and it should remain high for at least 1 microsecond.

Pin 18: MO On/OffThe NuQ pulsed laser manages the MO turn on and off internally. The MO On/Off signal input is ignored and can be in any state. Pin 19: FA On/OffA rising edge pin 19 will turn on the laser, while a falling edge turns it off.

Pin 20: PRR InputFor NuQ-20W-X-YAn input signal at the desired pulse repetition rate (PRR) is sent through this pin. This signal triggers the laser’s internal RF oscillator that feeds the Q-switch, and it should be a TTL square wave at 20 kHz to 100 kHz.If the frequency of this signal is less than 20 kHz, the laser will generate extra optical pulses at 20 kHz.Obviously this mode of operation should be avoided as the extra pulses will be asynchronous, and the pulse-to-pulse energy will be unstable.

For NuQ-30W-X-YAn input signal at the desired pulse repetition rate (PRR) is sent through this pin. This signal triggers the laser’s internal RF oscillator that feeds the Q-switch, and it should be a TTL square wave at 30 kHz to 100 kHz.If the frequency of this signal is less than 30 kHz, the laser will generate extra optical pulses at 30 kHz.Obviously this mode of operation should be avoided as the extra pulses will be asynchronous, and the pulse-to-pulse energy will be unstable.

2.3 Laser Installation

2.3.1 Mounting the Laser

Mount the NuQTM laser as desired using the bolt holes to firmly attach the unit to a surface or a marking system. Do not block the airflow to the cooling fans on the rear panel. The fans provide the desired flow to cool the diodes and other components in the laser to ensure longevity of the laser. Provide adequate room in front of the front panel to access the various connections.

2.3.2 Mounting the Termination Housing

The termination housing has a built-in isolator and a beam expander. The housing should be mounted in a manner such that there is minimal stress on the fiber delivery cable. The fiber delivery cable should be laid out to avoid excessive twisting and tight bend radii. The termination head should be mounted such that the laser output is directed in a manner that ensures no danger to personnel or property in the vicinity of the laser.

2.3.3 Electrical ConnectionsConnect the power cable per the pin-out is provided in Table 1 in section 3.2.1. Next connect the 25-pin Sub-D and/or the 9-pin Sub-D, depending on whether you will use the parallel interface, RS-232 interface or both. If you will gate the FA via the Gate BNC, then connect this signal. If you intend to use the PRR Out to synchronize other equipment or instruments, then connect to this signal.

2.4 Starting Up the Laser2.4.1 Laser Start-Up Using DB25 Parallel InterfaceOnce the laser module and termination assembly are properly mounted and the correct electrical connections are made, the laser is almost ready to run. In order to get the PFL to produce output, the following steps need to be completed.

1. Apply the appropriate voltages to the power cable, as described in Tables 1 and 6.2. Apply a TTL low signal to all signal inputs, pin #s 1–8, 9, 18–19, 22.3. Pin 23 must be high.4.1 For NuQ-20W-X-Y apply a Pulse Sync Signal on pin #20. This should be a TTL signal operating at 20 kHz to 100 kHz.

Do NOT operate this signal below 20 kHz. The laser will default to 20 kHz if no signal is applied.4.2 For NuQ-30W-X-Y apply a Pulse Sync Signal on pin #20. This should be a TTL signal operating at 30 kHz to 100 kHz.

Do NOT operate this signal below 30 kHz. The laser will default to 30 kHz if no signal is applied.5. Set the desired power of the laser using pins 1–8. The default is 0 W (MO only is on).6. Latch the power setting by toggling pin #9.7. Set pin #18 high to enable the MO. Wait at least 200 µs before setting pin #19 high. 8. Send a TTL high signal to pin #19 to turn on the laser.9. Turn the laser on and off with Pin #19.

APPENDIX C: EXTENDED WARRANTY

Nufern warrants the NuQ Fiber Laser to be free from defects in workmanship and materials, hereinafter called “Nonconformity,” for a period of twelve (12) months from the date of shipment or such other date set forth in the contract.

This warranty does not apply to systems which Nufern determines, upon inspection, have failed, become defective or unworkable due to abuse, mishandling, misuse, alteration (unless approved in writing by Nufern), negligence, improper installation, use which is not in accordance with the information and precautions described in the NuQ Operator’s Manual, or other causes beyond Nufern’s control.

Operating at above the maximum rated output power specified in Appendix A will void the warranty.

This warranty does not apply to (i) any products or components not manufactured by Nufern or (ii) any aspect of the products based on buyer’s specification, unless Seller has reviewed and approved such specification in writing.

EXCEPT FOR THE FOREGOING WARRANTY, NUFERN SPECIFICALLY DISCLAIMS AND EXCLUDES ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF NONINFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Buyer shall notify Nufern of any Nonconformity during the warranty period, obtain a return authorization for the nonconforming products, and return the nonconforming products, freight prepaid, to Nufern’s designated facility along with a written statement describing the Nonconformity. Nufern’s sole and exclusive obligation under this warranty is to use reasonable commercial efforts, at Nufern’s option, to repair, replace or refund the purchase price for any products which are returned to Nufern as set forth above and which are, after examination by Nufern, determined in Nufern’s reasonable discretion to be nonconforming. Products which are repaired or replaced within the warranty period are warranted only for the remaining unexpired portion of the original warranty period applicable to the repaired or replaced products or components. However, the warranty period does not include the time period between when Nufern receives the nonconforming products and when Nufern returns the repaired or replacement products to Buyer. Buyer agrees that the foregoing provisions constitute the sole and exclusive remedies available to Buyer for breach of warranty by Nufern with respect to the products.

IN NO EVENT WILL NUFERN BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO, LOSS OF ANTICIPATED PROFITS OR BENEFITS, EVEN IF NUFERN HAS BEEN INFORMED OF THE POSSIBILITY THEREOF IN ADVANCE. IN NO CASE WILL NUFERN’S AGGREGATE LIABILITY TO BUYER BE GREATER THAN THE PURCHASE PRICE PAID BY BUYER TO NUFERN FOR THE PRODUCTS WHICH ARE THE SUBJECT OF BUYER’S CLAIM.

The products are not authorized by Nufern for Buyer’s use in any device or application where the failure, malfunction or inaccuracy of the product carries a risk of death or serious bodily injury, such as, but not limited to medical equipment, nuclear facilities, aircraft operations, air traffic control, life support or other applications representing a similar degree of hazard.
