摘要
从Helmholtz方程出发,讨论了高斯光束在1+1维强非局域非线性介质中的传输特性及其光束束宽随位置的演化,即当介质的响应函数为高斯型时,用理论分析和数值模拟的方法,讨论了响应函数的特征宽度ωm对光束传输的影响.
Based on the H elmholtz equation, this paper discusses the property of Gaussian beam＇s transmitting in 1 ＋ 1-D strong nonlocal nonlinear media and the evolution of its width in accordance with the position. By using the method of theoretical analysis and numerical simulation, the influence of the feature width wm on beam transmission is studied, when the media response function is the Gaussian type.
