Thermal exthermal of KYb[x]Y[1-x](WO[4])[2] crystals

Abstract

Thermo-optic coefficients of the Er{3+}-doped gadolinium-yttrium oxyorthosilicate crystal Er{3+}:GdYSO are determined at a wavelength of 632.8 nm for light polarizations E // N[p], Nm and Ng. Linear thermal expansion coefficients are estimated for this crystal in the directions of the optical indicatrix axes Nm and Ng. Key words: monoclinic crystal, thermo-optic coefficient, (GdY)[2]SiO[5] crystal, thermal coefficients of the optical path.
