摘　　要：纯四次孤子光纤激光器是一种新型的超短脉冲激光器,能够在四阶色散和自相位调制效应平衡下保持脉冲形状稳定传输.相比于二阶色散主导下的常规孤子激光器,纯四次孤子激光器输出的锁模脉冲能量可以高出1-2个数量级,这将为研制高能量、高峰值功率的光纤激光器提供新思路.本文系统地回顾了近年来在光纤激光器等非线性光学系统中纯四次孤子的产生以及传输特性,并探讨了纯四次孤子中已观察到的一些特殊瞬态动力学现象.同时,介绍了笔者所在课题组在该研究方向上的最新成果.最后,本文对纯四次孤子光纤激光器的应用前景以及发展趋势进行展望,为相关领域未来的研究提供有价值的参考.这些结果将有助于更全面认识纯四次孤子光纤激光器的基本物理特性.The pure-quartic soliton fiber laser is an innovative ultra-short pulse laser that can maintain a stable pulse shape through a balance between fourth-order dispersion effect and self-phase modulation effect.Comparing with traditional soliton laser that is dominated by second-order dispersion,the mode-locked pulse energy of pure-quartic soliton laser can be 1−2 orders of magnitude higher.This provides researchers with new ideas for developing high-energy and high-peak-power fiber lasers.Here,the generation and transmission characteristics of pure-quartic solitons in nonlinear optical systems such as fiber lasers in recent years are systematically reviewed.It also explores some special transient dynamic phenomena.Furthermore,in this article,the latest achievements of our research group in this area are also presented.Finally,the application prospect and development trend of pure-quartic soliton fiber lasers are prospected.These results will contribute to a more comprehensive understanding of the basic physical properties of pure-quartic soliton fiber lasers.
