摘要

在线性温度梯度介质下，单斜KYbxY1-x (WO4)2晶体（x = 0、0.05、0.1、0.2、0.5和1.0）在波长1.06 μm处的E//Np、E//Nm和E//Ng光极化下的热光学系数。KYbxY1-x (WO4)2晶体采用改进的Czochralski法生长，采用动态生长机制和选择结晶前沿所需的温度梯度。结果表明，KYbxY1-x (WO4)2晶体的dni/dT系数（i = p, m, g）与化学计量系数x呈线性关系。

Thermo-Optic Properties of KYbxY1–x(WO4)2 Laser Crystals

Thermo-optic coefficients of monoclinic KYb_xY_1–x(WO₄)₂ crystals (x = 0, 0.05, 0.1, 0.2, 0.5, and 1.0) for E//N_p, E//N_m, and E//N_g light polarizations at wavelength 1.06 μm using the laser beam deflection technique for a medium with a linear temperature gradient. KYb_xY_1–x(WO₄)₂ crystals were grown by a modified Czochralski method using a dynamic growth regime and selection of the required temperature gradient at the crystallization front. The dn/dT coefficients obtained for all the polarizations are negative and their absolute values decrease with increasing coefficient x. The dni/dT coefficients (i = p, m, g) for KYb_xY_1–x(WO₄)₂ crystals were shown to depend linearly on their stoichiometry coefficient x.
