摘要 利用变分法研究了1+1维傍轴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以及空间孤子存在的条件,并对弱非局域非线性介质中的高斯型空间光孤子的稳定性进行了分析。 By the means of variational approach, the propagation properties of the 1 + 1 dimension paraxial Gaussian optical beam is investigated in the weakly nonlocal nonlinear media, the parameters evolution equation and the condition of existing spatial soliton is obtained, and the stability of the Gaussian shaped spatial soliton is analysed.
