非局域克尔介质中厄密高斯光束传输的变分研究

Nonlocal Kerr Media in the Gaussian Beam Propagation Hermitian Variational Study

利用变分法讨论了具有高斯响应的非局域非线性介质中高阶光束传输的物理特性。用数值解作为模拟光束传输的初始值,发现光束的传输特性随着非局域程度的改变而改变,当介质的非局域程度比较小时,厄密高斯光束分裂成为几个单独的光束传输,而当非局域程度比较大时,厄密高斯光束能够稳定的传输而保持宽度不变,形成孤子。

A variational method is discussed with the Gaussian response nonlocal nonlinear media in the physical characteristics of high beam transmission.Numerical simulation using beam propagation as the initial value of beam propagation characteristics found with the non-local level is changed,when the medium more hours of non-local level,Hermite Gaussian beam split into several separate transmission,and when relatively large non-local,Hermitian Gaussian beam to stabilize the transmission while maintaining the same width to form a soliton.
