Abstract

The thermo-optic coefficient of lithium niobate (LiNbO₃) has been measured in the temperature range from 10 to 160 °C using an interferometric setup. Undoped and magnesium-doped congruently melting LiNbO₃ and undoped stoichiometric LiNbO₃ were studied over a wide wavelength range in the visible and near infrared (450 – 600 nm and 900 – 1130 nm) using a frequency-doubled cw optical parametric oscillator. Experimental results for congruently grown lithium niobate were aggregated using a Schott equation to describe the wavelength and temperature dependence of the thermo-optic coefficient.
