Nd:YAG 100 W CW output laser with power supply, high voltage leads, and Wakefield Engineering heat exchanger. The laser cavity uses a single ARC lamp. All optics required to align and collimate the Nd:YAG beam and combine it with the beam of a pointing laser for delivery to an output fiber are included. The red HeNe pointing laser is a Melles Griot model 05-LHR-151. Its safety rating is 15 mW max and it is powered by a Melles Griot model 05-LPM-902-055 power supply. There are 3 beam blocking shutters, 1 solenoid used to insert 1 of 2 attenuators(?), 1 power sensor that reads directly from the cavity, and a second power sensor after the pair of solenoid positioned attenuators. There is also an interlock for the cover and there are two interlocks on the fiber collimator output connector. The 6 kW, Electronic Measurements, Inc. (now Lambda-EMI) model ESKI-150-40-2N-0704 arc lamp power supply requires single phase 208-220 VAC at 35 A for full output from the laser. The power supply has a DB-25 connector for remote programming. The Wakefield heat exchanger has a thermocouple, flow switch, and fan control module. Cooling water enters through the bottom of the laser and flows in series from the beam-dump to the cavity. There is a single thermocouple temperature sensor on the water line. The laser had 55 hours on the hours meter when disassembled. Weights: Laser - 35 pounds, Power Supply - 60 pounds, Cooler Assembly - 25 pounds, Pump - 50 pounds. |
