摘要

我们展示了一种利用受激布里渊散射（SBS）进行 Q 开关的简单全光纤铥（Tm）激光器。最大输出脉冲能量为 80 μJ。这使我们能够在激光输出端直接生成宽带光谱。我们首次以小于 100 ps 的分辨率测量了输出脉冲的精细结构。结果发现，SBS Q 开关激光器能够产生皮秒脉冲串。讨论了调制不稳定性对脉冲衰减的影响。研究还证明了所研究的激光辐射在对软生物组织产生破坏性影响方面的潜在应用。

Fine Structure of High-Energy Pulses from a Stimulated Brillouin Scattering-Assisted Q-Switch Tm-Doped Fiber Laser

We have demonstrated a simple all-fiber thulium (Tm) laser Q-switched by stimulated Brillouin scattering (SBS). The maximum output pulse energy was 80 μJ. This allowed us to generate a broadband spectrum directly at the laser outputs. For the first time, we measured the fine structure of the output pulses with a resolution of less than 100 ps. It was found that the SBS Q-switched laser is capable of generating bunches of picosecond pulses. The effect of modulation instability on the pulse decay is discussed. The potential application of the investigated laser radiation for producing destructive effects on soft biological tissues has been demonstrated.

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.
