Fluoride Crystals for High Peak Power Laser Window Coatings.

摘要

The development of high power lasers operating in the infrared has generated a need for improved window coating materials. Absorption at the laser wavelengths must be as low as possible to minimize heating and concomitant damage. Residual impurities in optical materials give rise to absorption bands and also raise the nonspecific infrared absorption above the intrinsic level.
