Abstract
We have measured the thermal expansion and the temperature dependence of z and y components of the refractive index for KTiOPO4and KTiOAsO4, in the wavelength range 532–1585 nm and temperature range 25–200 °C, using an interferometric technique. The measurements were used to derive temperature-dependent Sellmeier equations for the two materials. These equations predict with good agreement the temperature dependence of quasi-phase-matched nonlinear frequency converters.
