实验研究了y向切割掺杂铌酸锂晶体中入射光和反射光之间的光耦合 .当异常光分别沿 +y和 -y轴方向入射时 ,二者的透射率和反射率的时间行为基本一致 .而寻常光分别沿 +y和 -y轴方向入射时 ,二者的透射率和反射率的时间行为明显不同 .初步探讨了该现象的物理机理
The optical coupling between incident light and reflected light in the y-cut doping LiNbO3 crystal was experimentally studied.When the abnormal light is incident on the + y and -y axes respectively, the time behavior of transmittance and reflectivity While the ordinary light incident on the direction of + y and -y axis respectively, the time behavior of the transmittance and reflectivity of the two are obviously different.The physical mechanism of the phenomenon is preliminarily discussed
