Abstract

We studied the refractive index and dispersive properties of the tetragonal rare-earth calcium aluminates, CaLnAlO(4) (Ln = Gd or Y). Sellmeier equations were derived for the spectral range of 0.35-2.1 mu m. The group velocity dispersion (GVD) in CaGdAlO4 is positive at similar to 1 mu m, 95 fs(2)/mm and negative at similar to 2 mu m, -40 fs(2)/mm. The GVD values for CaYAlO4 are similar. In addition, thermo-optic coefficients, dn/dT, and thermal coefficients of the optical path were determined for CaYAlO4. dn/dT is negative at similar to 1 mu m, dn(o)/dT = - 7.8, and dn(e)/dT = - 8.7 x 10(-6) K-1. Thermo-optic dispersion formulas were constructed. The obtained data are of key importance to the design of high-power mode-locked oscillators at similar to 1 and similar to 2 mu m based on such laser hosts. (C) 2017 Optical Society of America
