Abstract

Transition metal dichalcogenides (TMDs) have increasingly attracted the interest of researchers due to their exceptional physical and chemical properties and broad application prospects. Currently, research on the application potential of the novel ternary TMD alloy MoWSe₂ as a saturable absorber (SA) is not yet mature. This artical achieves mode-locking for the first time after implementing Q-switching in MoWSe₂ SA. This study employed the liquid-phase exfoliation (LPE) method to fabricate a high-quality MoWSe₂ SA with a modulation depth of 7.9 % and a saturation intensity of 14.7 MW/cm². Stable conventional solitons (CS) and harmonic mode-locking (HML) of multiple orders were achieved. The highest order of HML reached the 86th order, with a maximum repetition frequency of 374.8 MHz. This represents the highest repetition frequency achieved to date in fiber lasers based on a MoWSe₂ SA. The results show that MoWSe₂ SA exhibits excellent nonlinear optical modulation performance, which lays the foundation for its role in advancing academic exploration and innovation in engineering practice in the field of ultrafast photonics.

基于MoWSe2饱和吸收器的被动锁模高重复频率脉冲光纤激光器

过渡金属二硫族化合物（TMDs）由于其特殊的物理化学性质和广阔的应用前景而日益引起研究人员的兴趣。目前，新型三元TMD合金MoWSe2作为可饱和吸收体（SA）的应用潜力研究尚不成熟。本文在mowse2sa中实现q交换后，首次实现了模式锁定。本研究采用液相剥离（LPE）法制备了调制深度为7.9%、饱和强度为14.7 MW/cm2的高质量MoWSe2 SA。实现了稳定的常规孤子（CS）和多阶谐波锁模（HML）。HML的最高阶达到第86阶，最大重复频率为374.8 MHz。这代表了迄今为止在基于MoWSe2 SA的光纤激光器中实现的最高重复频率。结果表明，MoWSe2 SA具有优异的非线性光调制性能，为其在超快光子学领域的学术探索和工程实践创新奠定了基础。
