Optical materials for 2 to 6 micrometers and 10. 6 micrometers high power lasers. Final report, 6 April 1975-30 September 1976
Several optical properties of materials suitable as components useable with CO/sub 2/ with ( 10.6 micrometers) and other chemical lasers (2 to 6 micrometers) are considered. Frequency and temperature dependence of absorption coefficient in the transparent regime of alkaline earth fluorides and mixed fluorides have been measured and understood on the basis of current theories and their desirability as window materials in the 2 to 6 micrometers region has been assessed. Lattice dynamics of mixed crystals and structurally disordered solids have been considered in the context of their phonon optical properties. The optical properties and electronic structure of amorphous semiconductors have been investigated emphasizing the changes relative to the ordered state resulting from the structural disorder. Also considered here are the properties, e.g., elasto-optic coefficients, responsible for beam distortion at high photon flux in an optical component.
