摘要
利用变分法研究1+2维傍轴Gauss光束在弱非局域非线性介质中的传输特性,得到了Gauss光束各参量的演化方程、空间光孤子及其存在的条件,并对Gauss型光孤子的稳定性进行了分析。
By means of variational approach, the propagation properties of the 1 ＋ 2 dimension paraxial Gaussian shaped optical beam is investigated in the weakly nonlocal media,the parameters evolution equation and the condition of existing spatial soliton is obtained,and the stability of the spatial soliton is analyzed.
