Abstract

The Thermo-Optic Coefficients, dn/dT and the Thermo-Polarizability Coefficients, dα/dT of Lithium rich LiNbO3, (mole ratio Li/Nb=0.996) grown by vapour transport equilibration are evaluated in the temperature range of 298K to 772K at λ=0.4545μm, λ=0.6328μm and λ=1.0642μm by using the Point Dipole Approximation and the appropriate Sellmeier equations. This work led to the estimation of possible set of polarizabilties of constituent ions of the crystal and their temperature dependence.
