摘要
运用变分法研究了1+1维sech型光束在具有e指数响应的弱非局域非线性介质中的传输特性,得到了光束各参量的演化方程和一个临界功率.当光束初始功率等于临界功率时,得到了一个稳定的sech型空间光孤子.
The propagation property of 1 ＋ 1 dimensional seeh optical beam is investigated in weakly exponential response nonloeal nonlinear media by means of variational method . The evolution equations of the parameters, and a critical power are obtained for the beam. a steady sech spatial soliton is found when the input power equals the critical power.
