Techniques for preventing damage to high power laser components

PDF Version Also Available for Download.

Description

Techniques for preventing damage to components of the LASL Shiva high power laser system were briefly presented. Optical element damage in the disk amplifier from the combined fluence of the primary laser beam and the Xenon flash lamps that pump the cavity was discussed. Assembly and cleaning techniques were described which have improved optical element life by minimizing particulate and optically absorbing film contamination on assembled amplifier structures. A Class-100 vertical flaw clean room used for assembly and inspection of laser components was also described. The life of a disk amplifier was extended from less than 50 shots to 500 ... continued below

The life of a disk amplifier was extended from less than 50 shots to 500 shots through application of these assembly and cleaning techniques. (RME)
