Abstract

Thermo-optic coefficients (dn/dT) determine the temperature characteristics of nonlinear-optical laser devices. These coefficients are analyzed critically by use of a new model for what is to the author’s knowledge the first time to find refractive indices at any operating temperature and wavelength for pure stoichiometrically grown LiNbO₃, LiIO₃, and LiTaO₃ crystals. This model is based on the thermal expansion coefficient, the temperature coefficient of the excitonic band gap, and a newly introduced isentropic band gap that lie in the UV region instead of on consideration of the spontaneous polarizability.
