Temperature dependence of LiTaO3 refractive index: Correction of Sellmeier equation
Abstract
We report a new and more precise Sellmeier equation derived using the quasi-phase-matching curves obtained from the study of the optical parametric generation (OPG) in 1D periodically poled LiTaO3 (1D-PPLT) of different periods at low and high pump power.
