Optical Pumps for Lasers

Abstract

The objective of the program is to increase both the output efficiency and the reproducibility of optical pumps for Nd:YAG lasers. Lamps with quartz envelopes dopes with cerium, which converts ultra violet radiation to visible radiation, have been tested and found to emit 15% more light in the region between 0.4 and 0.65 micrometers than lamps made of undoped quartz. An analysis was made of the externally triggered mode and simmer mode of flashlamp operation. A technique was devised to measure lamp arc growth during a pulse. A lamp of 4 mm bore diameter and 2.125 inch arc length, filled with 450 Torr of xenon, required a 20 joule pulse to fill the bore within a 100 microseconds period. Lamps have been manufactured to tolerances significantly tighter than normal; they may provide more reproducible light output than is provided by standard lamps.
