摘要
利用变分法研究了sech光束在弱非局域介质中的传输特性,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sech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 Sech shaped optical beam is investigated in the weakly nonlocal media, the parameters evolution equation and the condition of existing spatial soliton are obtained, and the stability of the spatial soliton is analysed.
