| 摘 要： | 基于模式分解方法, 分析了输入面纵向偏移诱导的强非局域非线性光传输特性变化的普适性规律. 结果表明光束输入面移动后导致的影响包括: 光斑在每个周期内出现的位置和顺序的变化、 相同形状的光斑在输入面移动前后大小的差异以及波面曲率因子的演化. 这些性质可用一个简单的数学公式进行归纳; 利用这一公式可方便地由输入面移动前的任意光束解得到输入面纵向移动后的光束解.

| Abstract: | Based on the approach of mode decomposition, the influence of the longitudinal shift of the entrance plane on the propagation properties of beams in strongly nonlocal nonlinear medium is analyzed. The shift of the entrance plane changes the order and the longitudinal position of beam patterns in a period, the size of patterns, and the radius of the cophasal surface. These properties can be described with a simple mathematical equation, therefore the beam solution after the entrance plane is shifted can be easily obtained from that before the entrance plane is shifted.
