摘要

理论和实验研究了扩散和光伏机理下LiNbO3晶体界面非线性表面波的传播. 改变传播常数可以得到不同振荡周期的表面波模, 光波的能量随传播常数的递增而单调地递增.本文的实验结果与理论分析能很好地符合. 实验结果还表明, 增加入射光功率可缩短表面波的产生, 增大入射光束与晶体正c轴的夹角(小于90°)可提高表面波的激发效率.

关键词:

The propagation of nonlinear surface waves along the boundary of LiNbO3 crystals with diffusion and photovoltaic nonlinearities is investigated theoretically and experimentally. Surface waves with different oscillating period are obtained by changing the values of the propagation constant, and the energy of surface waves would increase monotonically with the propagation constant. Our experimental results are in good agreement with the theoretical analysis. Experimental results show also that the generation of surface waves can be shortened by increasing the power of the input beam; and the excitation efficiency of the surface waves can be enhanced by increasing the angle (less than 90 degree) between the input beam and the crystal c-axis.
