Birefringence in gamma1-(Ga_xIn_1-x)_2Se_3 single crystals

Dispersion of birefringence in gamma(1)-(GaxIn1-x)(2)Se-3 (x = 0.1, 0.2, 0.3, 0.4) uniaxial crystals is studied at T = 295 Kin the spectral range 0.6-1.1 mum. The character of birefringence compositional variation at In --> Ga cationic substitution is shown to be determined by the compositional variation of the absorption edge transition contribution in resulting birefringence.
