摘要
通过数值求解非线性薛定谔方程 ,详细描述了圆对称超高斯光束在 Nd:glass介质中传输形成的自聚焦环。初始光束受到扰动后 ,环就会分裂形成强烈的细光束 ,显示出自聚焦环的不稳定性 ,细光束具有很大的峰值光强 。
Self-focusing rings of circle symmetric super-Gaussian laser beam (CS SGLB) with high intensity travelling in Nd:glass medium, are described in detail with numerically solutio n to the nonlinear Sch[AKo¨4]dinger equation. When a CSSGLB with initial perturbations travelling in this medium, the self-focusing rings are to be broken up and form high intense filaments. This phenomenon showed the instabilit y of the self-focusing rings .The high intensity filaments may destroy the medium.
