the optical films of some well established laser materials and as well as some other new
materials have also been probed. Materials such as Nd: Yttrium Aluminum Garnet (Nd:
YAG), Ti: Sapphire, NdF3 and YbF3 were deposited on BK7 type optical glass, fused silica
(Suprasil), Sapphire and YAG substrates by conventional electron beam evaporation
processes. In case of Nd: YAG, the films were prepared by using pure single crystals of Nd …
