摘要

在被动锁模光纤激光器中，铋作为可饱和吸收材料为超短脉冲的产生开辟了一条全新的途径。基于耦合非线性Schrödinger方程(CNLSE)，详细研究了超快脉冲的产生和传输特性，重点研究了二阶色散对脉冲宽度、能量和频谱的影响。本文通过改变群速度色散(从0.03 $\mathrm{p}\mathrm{s}^{2}/\mathrm{k}\mathrm{m}$到0.09 $\mathrm{p}\mathrm{s}^{2}/\mathrm{k}\mathrm{m})$)$，脉冲宽度和能量随色散的增加而增加。研究结果对无破波光纤激光器的设计具有一定的指导意义，也为实验控制脉冲宽度和能量提供了理论依据。

Theoretical Analyses of Pulse Evolution in a Passively Mode-Locked Laser

In passively mode-locking fiber lasers, bismuthene used as the saturable absorber (SA) paves a brand-new way for the ultra-short pulses’ generation. Based on the coupled nonlinear Schrödinger equation (CNLSE), the generation and transmitting characteristics of ultrafast pulse are studied in details, especially, the influence of the second-order dispersion on the pulse width, energy and spectrum. In this work, through changing the group velocity dispersion (from 0.03 $\mathrm{p}\mathrm{s}^{2}/\mathrm{k}\mathrm{m}$ to $0.09\mathrm{p}\mathrm{s}^{2}/\mathrm{k}\mathrm{m})$, the pulse width and energy increase with the increase of the dispersion. The results from this work can be regarded as guidance when designing a wave-breaking-free fiber laser and also provide a theoretical basis for the experimental control of pulse width and energy.
