Phase Studies, Crystal Growth, and Optical Properties of CdGe(As(1-x)P(x))2 and AgGa(Se(1-x)S(x))2 Solid Solutions.

摘要

Lattice constants, pseudobinary phase diagrams, crystal growth, and optical properties of the chalcopyrite CdGe(As(1-x)P(x))2 and AgGa(Se(1-x)S(x))2 solid solutions are reported. The type-II phase-matching angle for frequency doubling of 10.6-micrometers radiation has been measured for CdGe(As(1-x)P(x))2 crystals with x = 0,0.13, and 0.19. On the basis of the results, it is estimated that 90 degrees phase matching would be obtained for x approx. 0.3.
