Abstract

Temperature dependences of optical path difference δΔ_і and the relative changes in thickness δl_і/l of TGS crystals doped with L-valine are studied. Temperature dependences of the relative changes in refractive indices δn_і/(n–1) are calculated. The anisotropy coefficients of refractive indices А_n–1(Т) and linear expansion Аα(Т) are calculated, and a characteristic minimum of these dependences is found near the phase transition temperature.
