Abstract In this article, the peak-power expression of dissipative-soliton-resonance (DSR) pulse is derived, in a normal-dispersion fiber laser, by using the equation for the resonance curve and the relationship between the parameters of cubic–quintic complex Ginzburg–Landau (CGLQ) equation and the cavity parameters. According to the peak-power expression, the peak power of DSR pulses is inversely proportional to the average dispersion and the square of the gain bandwidth, is proportional to the square of the saturation power. That is to say, we can improve the peak power of DSR pulse in three ways: Firstly, increase the saturation power in the case of sinusoidal-saturable-absorber transmission curve; secondly, decrease the gain bandwidth properly; thirdly, decrease the average dispersion suitably. In addition, the further results of numerical simulations are obtained by using pulse-tracing technique, which are in good agreement with the theoretical derivation of peak power of DSR pulses. This means that our work can serve as a guideline to design high-peak-power DSR fiber laser.

正常色散光纤激光器耗散孤子谐振峰值功率的数值研究

摘要 在本文中，利用谐振曲线方程和三次-五次复数参数之间的关系，推导出了法向色散光纤激光器中耗散孤子谐振 (DSR) 脉冲的峰值功率表达式。 Ginzburg-Landau (CGLQ) 方程和腔参数。根据峰值功率表达式，DSR脉冲的峰值功率与平均色散成反比，增益带宽的平方与饱和功率的平方成正比。也就是说，我们可以通过三种方式来提高DSR脉冲的峰值功率：一是在正弦-可饱和-吸收体透射曲线情况下增加饱和功率；其次，适当降低增益带宽；第三，适当降低平均色散。此外，进一步的数值模拟结果是利用脉冲跟踪技术得到的，与DSR脉冲峰值功率的理论推导吻合较好。这意味着我们的工作可以作为设计高峰值功率 DSR 光纤激光器的指南。
