13 September 1989 An All Solid State CO2 Laser Driver

A new, all-solid-state pulse generator has been fabricated to meet the SDIO requirement for an efficient, reliable pulsed power source to pump CO2 discharge lasers. This SCR-commutated nonlinear magnetic pulse compressor will be fully-compatible with present CO2 laser radar sources and will serve as a basis for future drivers designed to power lasers for airborne and spaceborne applications. By employing SCRs rather than thyratron commutators, this pulser provides a significant decrease in the weight and volume and a significant increase in reliability over the current generation pulsed power drivers employed on CO2 lasers. For example the 150 joule, 10 pps, CO2 laser driver (COLD- I) weighs 85 lbs which is 50% lighter than projected pulser weights having the same characteristics. Also pulsers using this innovative technology have already demonstrated reliabilities of 1010 shots. At this juncture a breadboard pulser has been constructed and tested. The results of these tests will be presented. Future options for design changes and their impact on weight and reliability will also be discussed.
