Аннотация:The spectrum of reflection sapphire in the range of 2.5 - 25 microns was investigated. The literature data on the frequency-temperature dependence of the absorption coefficient in the region of 2.5 - 7 microns were analyzed. These dependencies were extrapolated to 10.6 μm. It is shown that the absorption coefficient in the region of 10.6 μm in the temperature range 300 - 2300 K has the value - β = (2 ÷ 3) × 104 cm-1. These data can be used for developing the technology of laser processing of sapphire, ceramic alumina and anodized aluminum alloy products.
