摘要

在这项研究中,我们研究了基于单模光纤-分级多模光纤-单模光纤(SMF-GIMF-SMF)结构作为光调制器的掺铒光纤环形激光器的多脉冲机制的演化过程和动态特性。利用调制深度约为 8.68% 的 SMF-GIMF-SMF (SMS) 器件的优异非线性光吸收特性,在低泵浦功率下即可观察到频率为 9.84 MHz 的稳定单脉冲模式锁定。此外,通过适当提高泵功率和仔细调节偏振态,单脉冲操作可以在峰值功率钳制效应的作用下演变为多脉冲机制。此外,我们还监测了多脉冲的单次时间演化,结果表明这种状态具有独特而有趣的时间特性,脉冲间隔可变,脉冲强度不一致,据我们所知,这在超快光纤激光器中尚属首次。此外,这项基于时间拉伸色散傅里叶变换方法的研究还表明,这些多脉冲由具有不稳定强度和可变脉冲能量的混沌波包络组成。我们相信,这些发现对于揭示超快光纤中迷人的非线性脉冲动态具有深远的意义。

Generation and Dynamics of Multiple Pulses in an Ultrafast Fiber Laser with a Single-Mode Fiber–Graded-Index Multimode Fiber–Single-Mode Fiber-Based Saturable Absorber
In this study, we have investigated the evolution process and dynamic characteristics of a multi-pulse regime in an erbium-doped fiber ring laser based on a single-mode fiber–graded-index multimode fiber–single-mode fiber (SMF-GIMF-SMF) structure as an optical modulator. By utilizing the excellent nonlinear optical absorption of the SMF-GIMF-SMF (SMS) device with a modulation depth of ~8.68%, stable single-pulse mode locking at the frequency of 9.84 MHz can be readily observed at low pump power. In addition, the single-pulse operation can evolve into a multiple-pulse regime on account of the peak-power-clamping effect via suitably raising the pump power and carefully regulating the polarization state. Further, the single-shot temporal evolution of multiple pulses is monitored, indicating that this state shows unique and interesting temporal characteristics with variable pulse separations and inconsistent pulse intensities, which, as far as we know, is the first such observation in ultrafast fiber lasers. Additionally, this study, based on the time-stretch dispersive Fourier transformation method, suggests that these multiple pulses consist of chaotic wave envelopes with erratic intensities and changeable pulse energy. We believe that these findings have profound implications for revealing fascinating nonlinear pulse dynamics in ultrafast fiber optics.

期刊介绍: Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
