Dielectric mirrors for high power laser applications

Development of low loss dielectric high reflecting mirrors for high power laser applications presents some problems in selecting suitable thin film materials and in understanding their optical constants. Some of these problems have been solved by a systematic study of the dependence of optical constants on different evaporation parameters for a number of thin film materials. Using the data thus obtained high reflecting dielectric mirrors for different laser applications in theuv, visible and near-infrared regions were successfully developed indigenously by the method of vacuum evaporation.
