q-高斯激光束在预等离子体通道中的孤立波
Solitary waves of q-Gaussian laser beam in a preformed plasma channel
摘要
Abstract
The electromagnetic solitary waves of q-Gaussian laser beam in a preformed parabolic plasma channel is investigated by means of the variational method.Compared with the electromagnetic solitary waves of Gaussian laser beam,the results show that there exist two kinds of electromagnetic solitary solutions for q-Gaussian laser beam in a preformed plasma channel,i.e.,the focusing and the defocusing electromagnetic solitary wave solutions.In the same laser amplitude and plasma background,the laser beam with lower q has a larger amplitude and a poorer numerical stability for the focusing electromagnetic solitary waves.However,for the defocusing solitary waves,the results are just opposite.关键词
