The research of the grow speed of AgGa_1-xIn_xSe₂ monocrystalline synthesized by Vertical Bridgman method

AgGa_1-xIn_xSe₂ is 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 AgGa_1-xIn_xSe₂ usually synthesize by vertical Bridgman method. However, the melting and crystallization point of crystal can be changed by different x value of AgGa_1-xIn_xSe₂. To synthesize high quality monocrystalline of AgGa_1-xIn_xSe₂ with 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.
