摘要
运用变分法研究了1＋2维厄米-高斯光束在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,得到了一个稳定的厄米-高斯型空间光孤子.
The propagation property of 1＋2 dimensional Hermite-Gaussian beam is investigated in weakly nonlocal nonlinear media by means of variational method.The evolution equations of the parameters,and a critical power are obtained for the beam.A steady Hermite-Gaussian spatial solution is found when the input power equals to the critical power.
