The principal refractive indices and nonlinear optical phase matched properties of Nb:KTP crystals
Source abstract
Abstract
According to the supposition that the principal refractive indices are linear relation to Nb concentration in Nb:KTP crystal, we calculated the principal refractive indices of 3, 5, and 10 mol% Nb:KTP crystals for the wavelengths of 539.75, 632.8, 1079.5 and 1341.4 nm on the basis of the principal refractive indices of KTP and 7.5 mol% Nb:KTP crystals. We also obtained the Sellmeier equations of these crystals. The calculated optimal type II second harmonic generation phase matched angles of 1.0642 μm Nd:YAG laser and 1.0795 μm Nd:YAlO3 laser on the basis of these Sellmeier equations agree well with the measure values. The maximal deviation of these angles is no more than 0.67°.
