摘要
应用折射率椭球理论分析了线性电光效应,结合横向电光调制的相位延迟,得出铌酸锂晶体相关电光系数的测量方法,并采用直接测量半波电压法中的极值法和调制法分别测得铌酸锂晶体的相关电光系数,进行了测量结果对比分析。
The theory of refractive index ellipsoid is used to analyze the linear electro-optic effect,and combined with the phase delay of transverse electro-optic modulation,the measurement method of correlation electro-optic coefficient of LiNbO crystal is obtained.The related electro-optic coefficients of LiNbO crystal were measured by the extremum method and modulation method of the direct measurement of half wave voltage,then compare and analyze results.
