Growth and optical properties of the $AgGa_{1-x}In_xS_2$ system

A study was made of the growth conditions for the $AgGa_{1-x}In_xS_2$ system and single crystals with the compositions $x=0,08;0,2$ and $0,6$ were grown. The absorption coefficients and the refractive indices were measured in the range $0,55-11,5\mu m$. The wavelength dependences of the refractive indices were approximated by the Sellmeier polynomials. The phase matching diagrams were plotted for the $oo-e$ frequency mixing process. A study was made of the influence of the percentage amounts of gallium and indium in these single crystals on the phase-matching conditions.
