  • Page 11: A Brief Description Of The Laser

    4.0 A Brief Description of the Laser 4.1 ULR OEM Lasers The ULR-250/ULCR-500 OEM CO gas lasers use a sealed, RF excited, slab design incorporating an unstable resonator. Each laser consists of a plasma tube, with mirrors at each end forming an optical resonator, and an integrated RF power supply incorporated into the laser chassis which includes an integrated cooling fan.

    5.0 OEM Laser Installation and Operation 5.1 Laser Mounting There are threaded holes used for mounting located in the mounting pads in the bottom of the both the ULR-250 and ULCR-500 OEM lasers, as shown in the figures in Section 2. The laser can be mounted in any orientation including vertical.

  • Page 13: Communications Connections, Ulr/Ulcr Lasers

    5.3 Communications Connections, ULR/ULCR Lasers All communication connections for the laser are made through one 12-pin communications connector located on the back of the laser. The mating connector will accommodate up 22 AWG [0.33 mm2] wire. Figure 3 details the connector pin diagram. Figure 4 details the signals for each pin.

    No internal connection No internal connection Notes: Pins 4 & 6 are internally connected to “GNDIO”. The “GNDIO” signal should be connected on the driving electronics side. This shared signal is used as the return signal for all I/O. The “GNDIO” signal is optically isolated and NOT connected to the laser’s chassis or DC GND.

  • Page 17: Laser Operational Signals

    5.6 Laser Operational Signals A "laser status" signal is provided on pin 9 for diagnostic purposes (pin 11 is the return). During a fault, the laser will not operate. Possible detected faults include: Interlock circuit open; Over-temperature; Under-temperature; Failure in the internal power circuit. recommend not using this pin to save wire harness complexity, and instead poll results over RS485.

  • Page 18: Air Cooling

    6.0 Air Cooling 6.1 Proper airflow Careful attention should be paid to proper airflow through the laser when integrating it into equipment. Any restriction of airflow will result in reduced power output and can cause permanent power loss or failure over extended periods of time. Ambient air should be directed to the laser’s intake vents on the front end of the laser, and exhaust air from the back end of the laser should be directed out of equipment with as little restriction as possible.

    APPENDIX A: ULR250/ULCR500 (UL-10 RF Power Supply) Laser Serial Communications Protocol This document describes and defines the protocol to be used when communicating with ULR250/ULCR500 lasers. The protocol is implemented on top of an RS485 physical link. A master RS485 device will initiate queries and the laser (slave device) will start to respond to each query within 5mS.
