Abstract

The principal refractive indices and the thermal refractive-index coefficients of 7.5-mol.% Nb:KTiOPO4 crystal were measured by autocollimation for wavelengths of 0.53975, 0.6328, 1.0795, and 1.3414 µm from room temperature to 143 °C. The Sellmeier equations at room temperature were obtained and used to calculate the optimal phase-matched angles for 1.0642 and 1.0795 µm. The calculated and experimental values are in good agreement.
