摘要
从理论上对激光处于电场中的旋光晶体传播方程进行了研究,应用琼斯距阵理论分析了入射到晶体表面和透过晶体的光的偏振态,推导出了透过晶体出射的光为线偏振的条件,利用旋光晶体电光系数γ_(11)与施加电场的电压V和晶体角度α的关系,通过实验,测量了La_3 Ga_5 SiO_(14)晶体电光系数γ_(11)为2．2×10^(-12)m/V．
We study the propagating function of laser light through an optical activity crystal in electrical field. By analyzing the polarization states of input and emitted laser light with Jones formalism, the conditions of linearly polarized light are derived, According to the relationship between the electro -optical coefficient γ11 and the voltages of applied electrical field and the angles of the crystal La3 Ga5 SiO14 （LGS） resrectively, the electro -optical coefficient Yll is measured. The experiment result shows that the coefficient Y11 is 2.2 ×10^-12m/V.
