MATERIALS FOR HIGH-POWER CO2 LASERS.

Abstract

The report discusses window and mirror materials suitable for high-power 10.6 micron operation. An extensive survey of candidate materials is presented, including all pertinent physical parameters, as well as an assessment of the ultimate power-handling capabilities of each. Experimental measurement of the optical absorption coefficients was carried out wherever necessary. Major emphasis was placed upon the semiconducting window materials because of their superior mechanical properties. The thermal runaway mode of failure, characteristic of these materials, was analyzed in some detail for germanium, indium antimonide and gallium arsenide. The primary conclusions are that gallium arsenide remains the best candidate material for high-power windows and that indium antimonide is an interesting and very promising candidate for 'high-power' 10.6 micron optical isolator applications.
