| Abstract: | The piezobirefringence of uniaxial γ1-(GaxIn1?x )2Se3 crystals (x=0.3, 0.4) was investigated in the spectral range 0.6–1.1 µm at temperatures from 77 to 295 K. It is shown that uniaxial compression leads to a linear decrease in the birefringence, whereas a decrease in temperature reduces the effect of piezobirefringence. The baric changes in the birefringence are attributed to the baric changes in the contribution of the edge transitions to the total birefringence. |
