摘要
回顾了锁模光纤激光器中各种孤子动力学特性的研究状况,介绍了近年来基于色散傅里叶变换(DFT)技术的超快光纤激光器孤子瞬态动力学特性的研究进展,分析了同时利用时间透镜和DFT技术的超快现象多尺度探测,这些均有助于更全面地了解光孤子的物理本质。实时测量技术的发展必将极大地激发研究人员探索孤子动力学特性的热情,进一步促进孤子动力学特性研究和超快激光技术的发展。
The investigation of various soliton dynamics in a mode-locked fiber laser is briefly summarized,especially the recent progress of soliton transient dynamics in an ultrafast laser based on the dispersive Fourier transformation(DFT)technique is introduced.In addition,the multi-scale detection of ultrafast phenomena simultaneously using a time lens and the DFT technique is also briefly discussed,which helps to completely understand the physical nature of optical solitons.The development of real-time diagnostic methods can greatly inspire researchers to explore the soliton dynamics,and thus further promote the investigation of soliton dynamic characteristics as well as the development of ultrafast laser technologies.
