Abstract

Rare earth fluoride YbF₃ has been investigated as possible substitute materials for standard thorium fluoride layers in infrared laser optical components. All dielectric multilayer high reflective coatings with 3.8 micrometer and 0.6328 micrometer two wavelengths consisting of alternative ZnS and YbF₃ materials are presented in this paper. The deposition process and physical properties of YbF₃ coating have been studied. The performance measurements and damaged thresholds of the reflector are reported at .3.8 micrometer.
