摘要
运用变分法研究傍轴椭圆高斯光束在具有椭圆对称响应函数的强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演化规律.在强非局域非线性介质的椭圆对称响应函数的特征参量满足一定条件下,得到了一个临界功率,当光束初始输入功率等于临界功率时,可以得到变分椭圆高斯型空间光孤子.
The propagation of elliptically Gaussian beam in strongly nonlocal medium with elliptically symmetric response is discussed with a variational approach. A set of parameters evolution equations and parameters laws are obtained. The critical power is obtained by satisfying a certain condition of the material property parameter of strongly nonlocal medium. The ellipfically Ganssian spatial optical soliton is found when the input power equal to the critical power.
