摘要 介绍了在实验中观察到的类双环状结构调制激光束在克尔介质中的自聚焦现象 ,并在理论上 ,通过建立一个调制光束模型 ,运用数值求解非线性Schr¨Odinger方程 ,详细描述和解释了这种调制光束自聚焦形成的过程及其特点 ,最后还对双环间的耦合效应进行了研究 。 The self focusing effect of quasi double ring modulated laser beam propagating in the Kerr medium CS 2 has been observed in the experiment. In theory, the nonlinear Schrdinger equation is solved by means of setting up a modulated laser beam model. The forming process and the characteristics of the self focusing are described in detail. Finally, the coupling effect of the double ring laser beam has been investigated and the characteristics are given.
