Paper Abstract

The temperature coefficients of refractive index for various crystalline and polycrystalline materials, Al203 (ordinary ray), Y203, LaO3-dOped Y203, ALON, and MgA12O4 were determined from measurements of optical thickness as a function of temperature using a Michelson interferometer operating at 0.633 pm. For the temperature range of 23°C to 500°C, the first order coefficients ranged from 8.28x10I0C for pure yttria to 14.6x10/°C for ALON. Measurements of NaC1 and A1203 samples using this technique are in agreement with published data.
