The performance of repetitively pulsed, 70 joule, closed cycle 1.3 uM photolytic atomic iodine laser with excellent beam quality (BQ = 1.15) is presented. This BQ was exhibited in the fundamental mode from a M = 3.1 confocal unstable resonator at a 0.5 Hz repetition rate. A closed cycle scrubber/laser fuel system consisting of a condensative-evaporative section, two Cu wool 12 reactor regions, and an internal turbo-blower enabled the laser ...
A transverse flow continous wave atomic iodine laser system uses a closed cycle fuel system to operate in a continuous mode. An elliptical pump cell having a Hg arc lampo cooled by deionized water irradiates with UV energy C3F7I gas to produce excited atomic iodine. A transverse flow section attached to the pump cell channels C3F7I gas into a laser cell where lasing occurs. The flow section has upstream and ...
