Abstract
Estimations are carried out on creation possibilities of all solid state laser sources capable significantly or fully to solve the problem of designing a universal Aerosol-Gas Lidar System. The best existing solid state Nd:YAG and Ho2+ :ILF lasers supplied with frequency converters to middle JR are considered. Well known GaSe crystals with modernized properties by indoping and annealed ZnGeP2, little known HgGa2S4 and LiInS2, mixed AgGaIn(I-X)Se2, and new mixed AgXGaXGe(1-X)S4 and Hg(1-X)CdXGa2S4 nonlinear crystals are proposed as basic elements of these frequency converters. Optical properties and potential of these crystals are investigated and presented in details. The investigation results show that development of super wide band UV to FIR laser source can make it possible to carry out with efficiencies of one-two to several tens percent in several ways, using both the proposed and the traditional KTP, KTA, and BBO frequency converters.
