I'm posting this for a friend of mine who needs immediate assistance with his G100. Any help is greatly appreciated.

Thank you.

"Greetings everyone, I am the proud owner of a Coherent G100, (see: http://nilno.com/cgi-bin/laser_head.cgi) an RF excited sealed industrial C02 pulsed laser. It consists of 100 watt laser resonator and solid state RF amplifier integrated into an all aluminum enclosure. The RF amplifier provides pulsed RF power to the laser to ionize the CO2 gas mixture in the tube. Unfortunately the digital signal board in the laser appears to be dead. I have contacted one third party repair shop that said they can not replace boards, boards must be installed by Coherent. Coherent reports they may not have any boards, and at a minimum it will cost me $1,000 to have them open the head. I am querying this group to ask if anyone has another G100 that I might use for parts, or has other suggestions for repair. Yes, if coherent tells me they dont have any more boards in stock I may open up the device myself and attempt a repair."
