Frequency up-conversion in a mercury thiogallate crystal

Abstract

The effect of polymorphous transitions on the regularities of the scattering of Ar ions by polycrystalline cobalt has been studied. The temperature dependence of the number of ions scattered in a given direction has been established to be non-monotonic in the temperature range near the phase transition temperature.

“…For instance, they are widely used as non-linear optical materials (HgGa 2 S 2 and Cd 1−X Hg X Ga 2 S 4 [1,2]), as photosensitive materials (ZnGa 2 Se 4 [3]), or as narrow-band optical filters (CdGa 2 S 4 [4]). An important feature of these compounds is their low sensitivity to impurities and high resistance to ionizing radiation [5].…”
