非线性光学薄膜输出特性的研究

对单层、双层非线性光学薄膜的输出特性进行数值计算,发现材料非线性特性对光学双稳态输出特性影响较大,而选择合适的双层结构可以获得较低的双稳态阈值光强以及光放大作用。双层非线性光学薄膜间的距离以及入射光的准直性极大地影响着双稳态输出特性.

STUDY ON OUTPUT CHARACTER OF NONLINEAR OPTICAL FILM

Optical output character of one-layer and two-layer nonlinear optical film andayased by numeric method is given to indicate that:the material nonlinearity has a great influence upon optical ouput character; the lower bistability threshold value light intensity and character of amplifing light intensity are chained by chosen suitable two-layer strcuture; otherwise, adjusting the distance between two nonlinear optical films and collimation of input light can improve the optical bistability output character.
