据我们所知，我们首次报告了在 1.55 µm 的全少模光纤 8 字激光器中可切换生成多功能飞秒和皮秒时空锁模 (STML) 脉冲。在飞秒和皮秒脉冲体制下，激光器都具有脉冲模式可调谐功能，即脉冲模式可以从单脉冲、多脉冲到孤子分子进行调谐。特别地，飞秒孤子分子在松散束缚态下工作，而皮秒孤子分子可以在松散束缚态和紧密束缚态下工作。进行理论分析是为了进一步了解飞秒和皮秒脉冲的可切换生成。研究发现，非线性放大环镜（NALM）的滤波效应在飞秒脉冲的产生中起主要作用，而有源少模光纤-无源少模光纤结构引起的多模干涉滤波效应在皮秒脉冲的产生中起主要作用。所获得的结果有助于进一步探索STML光纤激光器的特性，这种具有多功能飞秒和皮秒脉冲可调谐输出的激光器在光通信、激光加工和测量方面具有潜在的应用。
We report, for the first time to the best of our knowledge, the switchable generation of versatile femtosecond and picosecond spatiotemporal mode-locked (STML) pulses in an all-few-mode fiber figure-8 laser at 1.55 µm. Both in the femtosecond and picosecond pulse regimes, the laser has pulse-pattern-tunable function, namely, the pulse patterns can be tuned from single-pulse, multiple pulses to soliton molecules. Particularly, the femtosecond soliton molecules operate at the loosely bound states while the picosecond soliton molecules can operate both at the loosely and tightly bound states. The theoretical analyses are carried out to give the further insight in the switchable generation of the femtosecond and picosecond pulses. It is found that the filtering effect of the nonlinear amplifying loop mirror (NALM) plays the major role in the generation of the femtosecond pulses while the multimode interference filtering effect induced by the active few-mode fiber-passive few-mode fiber structure plays the role in the generation of the picosecond pulses. The obtained results contribute to further exploring the characteristics of the STML fiber laser and such a laser with tunable output of versatile femtosecond and picosecond pulses has potential applications in optical communications, laser processing and measuring.
