Niobium diselenide (NbSe₂), an emerging group VB transition metal dichalcogenide, has been widely used in materials science, chemistry, and physics, while the applications of NbSe₂ in ultrafast photonics are still rare. In this study, a NbSe₂-based saturable absorber (NbSe₂-SA) is proposed by depositing NbSe₂ nanosheets on the surface of a microfiber, whose modulation depth is up to 8.8%. Based on the NbSe₂-SA, conventional solitons with an ultrashort pulse duration of 697 fs are achieved, which are proved to be polarization-locked vector solitons by further study. The results show that group VB transition metal dichalcogenides, including NbSe₂, could be developed as effective SAs for generating ultrafast pulses, especially vector pulses.

用于矢量孤子光纤激光器的二硒化铌纳米片

二硒化铌（NbSe ₂）是一种新兴的VB过渡金属二卤化_二硫化钨，已广泛用于材料科学，化学和物理领域，而NbSe ₂在超快光子学中的应用仍然很少。在这项研究中，提出了一种基于NbSe ₂的可饱和吸收剂（NbSe ₂ -SA），该方法是将NbSe ₂纳米片沉积在调制深度高达8.8％的微纤维表面上。基于NbSe ₂ -SA，获得了具有697 fs的超短脉冲持续时间的常规孤子，经进一步研究证明是偏振锁定矢量孤子。结果表明，包括NbSe ₂在内的VB族过渡金属二卤化物可以被开发为有效的SA，用于生成超快脉冲，尤其是矢量脉冲。
