Abstract

The output mirror is the most important optical component in determining laser beam quality. The mirror of an industrial laser is therefore the critical component of a high value system in a large market. XEMET's technology creates mirrors that not only resist thermal distortion by removing several KW/sq-cm., but also detects distortion and acts to off-set it in real time, holding the mirror shape invariant under very high pulsed loading. In addition to reducing the errors of the optical train, the mirrors will be very resistant to catastrophic damage. The technology is completely passive and does not require support equipment and does not introduce jitter as do other approaches.
