| 摘 要： | 本文提出一种以长程表面电磁激元波作为泵波,在非线性介质膜中实现简并四波混频的新方案。我们借助于将介质膜内曲折光线在一个方向上展开,获得系统的一维耦合方程,并得到了方程的解及共轭波转换效率的表达式。估计应用这种方案,采用波长合适、功率为1W量级的连续激光可有效地研究一些有机薄膜的三次非线性光学性质。

| Abstract: | We propose a new method to realize degenerate four-wave-mixing in nonlinear optical thin films using long-range surface-plasmons-wave as pumps. The coupled equtions of one dimension and their solutions are obtained by means of extending zig-zag ray in the thin film layer along one direction. Some properties about conversion effeciency of a conjugate wave are discussed. Effeciency (larger than 1) is estimated in some organical thin films using a CW laser with power of 1W and a suitabe wavelength. |
