Abstract

The absorption coefficients of mixed silver halide crystals and fibers were measured by different laser calorimetric methods: adiabatic for crystals and isothermal for fibers. The composition dependence of the bulk absorption coefficients βb of crystals and polycrystalline fibers at 10.6-μm (CO2 radiation) was investigated. It was found that the crystal surface absorption βs is dependent on the surface polishing quality. All experimental results of βb are smaller than those reported in the literature.
