| 摘 要： | 利用变分法研究了1＋1维傍轴高斯光束型在含有小损耗的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。在介质损耗足够小的前提下，当光束初始功率等于临界功率时，得到了一个束宽随传输距离缓慢展宽的准空间光孤子——损耗空间光孤子。

| Abstract: | The propagation property of 1+1 dimensional Gaussian beam is investigated in small lossy weakly nonlocal nonlinear media by means of variational method.The evolution equations of the parameters and a critical power are obtained for the beam.In the case of small loss,a lossy optical spatial soliton with beam width slow diffraction is found when the input power equals to the critical power. |
