摘要: 基于非线性Schrdinger方程模拟了Kerr介质中强光束局部小尺度调制致光束多路成丝现象，发现在一定的B积分范围内，光束局部小尺度调制基本上只从该局部本底场中吸收能量获得增长，从而将该局部光束分裂成细丝.当光束不同部分的小尺度调制相隔较远时，各 细丝的演化基本上不相关.

Abstract: Based on the nonlinear Schrdinger equation,we have simulated the multiple filamentation of locally modulated laser beams,and found that for B integral smaller than some values the local modulations grow to form filaments mainly by drawing energy from that part of background beam;the evolution of two parts of local modulation are basically independent if they are sufficiently far away from each other.
