Abstract

Dispersion of the principal refractive indices of pure and Yb3+ (20 at.%)-doped KY(WO4)2 crystal is obtained in the visible range of the spectrum. A comparatively strong increase of the refractive indices (0.0050.007) was observed for the doped crystal. Temperature dependence of the principal refractive indices is measured in the temperature region of 290690  K. Thermo-optical coefficients (TOCs) of the first dn/dt and the second (1/2)(d2n/dT2) order are determined. It is found that TOCs are negative for np and ng and positive for nm in both crystals. Doping increases dnp/dT almost two times more in comparison to that of the pure crystal, while for the other two indices TOC changes are insignificant.
