【 摘 要 】

AgGa1-xInxSe2is an infrared non-linear optical crystal which has been widely used in laser radar, infrared laser distant control and atmosphere environment monitoring area. The monocrystalline of AgGa1-xInxSe2usually synthesize by vertical Bridgman method. However, the melting and crystallization point of crystal can be changed by different x value of AgGa1-xInxSe2. To synthesize high quality monocrystalline of AgGa1-xInxSe2with one sure x value, we should measure the melting point and crystallization point, calculate the degree of super-cooling, to design suitable temperature field distribution for this crystal.
