Abstract
An effective nonlinear optical coefficient optimization method for langasite group solid solution crystals is disclosed. The langasite group crystal ABCDOmainly includes langanite (LGN) crystal, langatate (LGT) crystal and langasite (LGS) crystal. The solid solution crystals are formed by adjusting a component proportion of langasite group crystals with the same structure, so that different ions mix and occupy sites in a polyhedral group, and a polyhedral lattice structure, distortion degree, refractive index and refractive dispersion of the solid solution crystal are changed. The reduction of the phase matching angle and the improvement of the nonlinear optical coefficient are realized, and the effective nonlinear optical coefficient is finally optimized.
