The thermal dependence principal refractive indices of La2CaB10O19 (LCB) crystal at wavelengths of 0.254, 0.365, 0.405, 0.480, 0.546, 0.644, 0.852, 1.014, and 2.325 μm were accurately measured by using the vertical incidence method within the temperature range from 25 to 170 °C. We derived equations of thermal refractive index coefficients as a function of wavelength that could be used to calculate the principal thermal refractive indices at different wavelengths. The temperature-dependent Sellmeier equations were also derived and used to calculate the phase-matching angles for the third-harmonic generation of LCB crystal at different temperatures. Theoretical and experimental phase-matching angles for the type I third-harmonic generation of LCB crystal at different temperatures were in good agreement.
