Abstract

In our work, based on a high-damage-threshold MoS saturable absorber (SA), high-power intra-cavity Raman solitons within a passively mode-locked Yb-doped fiber laser were demonstrated successfully for the first time. The damage threshold of the MoS SA was as high as ~0.48 J/cm. By adjusting the polarization states, stable single- or dual-pulse Raman soliton operations were obtained. The maximum average output power for single-pulse and dual-pulse Raman soliton operations was 80.11 and 89.33 mW, respectively. Our experiment results show significant enhancement in comparison with previous works, which provides fundamental guidance for future designs of high-power, large-energy, intra-cavity Raman soliton generations based on two-dimensional materials as SAs.

摘要

在我们的工作中，基于高损伤阈值的二硫化钼可饱和吸收体（SA），首次在被动锁模掺镱光纤激光器中成功实现了高功率腔内拉曼孤子。二硫化钼可饱和吸收体的损伤阈值高达约0.48 J/cm²。通过调整偏振态，获得了稳定的单脉冲或双脉冲拉曼孤子运转。单脉冲和双脉冲拉曼孤子运转的最大平均输出功率分别为80.11和89.33 mW。我们的实验结果与之前的工作相比有显著提升，这为未来基于二维材料可饱和吸收体的高功率、大能量腔内拉曼孤子产生的设计提供了基础指导。
