| 摘 要： | 通过数值求解非线性近轴波方程, 研究了在等离子体中传输的超高斯强激光的自聚焦行为. 结果表明, 自聚焦形成的环在初始光束受到扰动时出现环分裂的现象, 同时由于自由电子的散焦作用, 使得自聚焦环被限制在某一特征尺度内.

| Abstract: | The behavior of self-focusing of the ultra-intensity rotation symmetric super-Gaussian beam (RSSGB) during propagation in the plasmas is studied,with the aid of the numerical solution to the nonlinear paraxial wave equation.The result implies for a RSSGB with initial undulations,the self-focusing ring may split after traveling certain distance inside the plasmas.And because of the effect of the defocusing free-electron,the self-focusing ring is limited within a certain scales. |

| Keywords: | plasmas self-focus Kerr effect super-Gaussian beam |
