摘要

为进一步研究非线性渐增光纤中超短脉冲自相似演化的特性

利用数值仿真的方法分析了入射脉冲能量、脉冲宽度和类增益系数3个因素对输入脉冲自相似演变的影响。结果显示:入射脉冲能量和类增益系数对自相似演变的影响较为显著

在增大入射脉冲能量或类增益系数的情况下均可加速自相似演化的速度

即缩小演化所需的特征距离;而脉冲宽度对自相似演化的速度影响则十分微弱。

Abstract

To further study the characteristics of self-similar evolution of the ultra-short pulses in nonlinearity-increasing fibers

the influences of incident pulse energy

pulse width and equivalent gain coefficient on the evolution are analyzed by using the numerical simulation method.The results show that both the incident pulse energy and equivalent gain coefficient have obvious influences on the self-similar evolution

in that the evolution speed increases when pulse energy or equivalent gain coefficient is increased

i.e.the characteristic length that the evolution needs is shortened

while the influence of pulse width is feeble.
