Abstract

We studied the refractive index and dispersive properties of the tetragonal rare-earth calcium aluminates, CaLnAlO4 (Ln=Gd or Y). Sellmeier equations were derived for the spectral range of 0.35–2.1 μm. The group velocity dispersion (GVD) in CaGdAlO4 is positive at 1  μm, 95  fs2/mm and negative at 2  μm, 40  fs2/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 1  μm, dno/dT=7.8, and dne/dT=8.7×106  K1. Thermo-optic dispersion formulas were constructed. The obtained data are of key importance to the design of high-power mode-locked oscillators at 1 and 2  μm based on such laser hosts.
