基于铌酸锂晶体电光效应的差频转换效率调制
Conversion efficiency modulation of difference-frequency generation based on electro-optic effect in lithium niobate crystal
摘要
Abstract
It is always expected that the conversion efficiency is as high as possible for nonlinear interaction at any pump intensity. A method was presented to control the conversion efficiency of difference-frequency generation ( DFG) in the periodic poled lithium niobate, by modulating the refractive index induced by electro-optic effect. The variation of DFG conversion effieciency with the external electric field was simulated. The calculated results indicate that this method is feasible and very efficient in attaining the high conversion efficiency at any given pump intensity. This result is very useful to get new lasers especially in mid-infrared region.关键词
