Research Institution
AgGa(1-x)InsSe2 is a unique nonlinear crystal suitable for a wide range of 3-wave mixing applications, including co2 laser NCPM SHG and THG. It combines strong nonlinear coupling with phase-matching across a wide (0.8-13um) transmission range. These properties also provide the basis for near-IR pumped OPO and DFG systems generating tunable laser radiation from ~2.0 to 13 um. When combined with demonstrated SFG techniques, the range of available wavelengths is extended to the eye safe region. In addition to CO2 lasers for SHG/THG, solid state 2 and 3um lasers may be used for OPO and DFG systems. CCI has grown low absorption AgGa(1-x)InxSe2 using AgGaS2 and AgGaSe2growth-technology. However, material must be grown with a variety of In concentrations and in sufficient volume to allow material characterization and to establish production parameters. The goal would be to establish preliminary production of low (0.005-0-0.15cm1) bulk absorption crystals, similar to the current range of production AgGaSe2. During Phase I, low absorption/scatter crystals would be grown and processed for testing. Emphasis would be placed on obtaining uniform doping levels at x~40%. Phase II would include continued analysis of crystal characteristics and development of a standardized production process. The goal would be to attain routine production of low absorption/scatter AgGa(1-x)InxSe2 at the desired In concentration.
