摘要

Orientation of the principal optical axes, dispersion of the refractive indices along the three principal optical directions in the spectral range of 480–1014 nm, thermal expansion coefficients for directions along optical indicatrix axes Np and Nm, and the principal thermooptic coefficients at a wavelengths of 632.8 nm and 1064 nm are determined for Yb3+:Gd2−xYxSiO5 (x = 0.385) monoclinic crystal (space group of P21/c). The principal thermooptic coefficients are found to be negative. Thermal lensing was characterized in a continuous-wave Np-cut, Nm-cut, and Ng-cut Yb3+:Gd1.615Y0.385SiO5 diode-pumped at wavelength of 0.976 μm and operating at wavelength of 1.090 μm. The measured thermal lens is found to be positive. The sensitivity factors of the thermal lens were obtained.
