摘要
As a representative transition metal dichalcogenides(TMD),NiTe_(2)has an ultra-fast optical response,high carrier mobility,and excellent environmental stability.It has a broad application prospect in the fields of ener-gy,biomedicine,optoelectronic devices,and so on.At present,there have been scant reports on the application of NiTe_(2)in the field of ultrafast photonics.In this work,NiTe_(2)was synthesized by chemical vapor deposition(CVD)and integrated with a tapered optical fiber to achieve mode-locking in an erbium-doped fiber laser(EDFL)and a thu-lium-doped fiber laser(TDFL).The mode-locked EDFL exhibited a pulse width of 678 fs and an output power of 3.92 mW.The pulse width of mode-locked TDFL was estimated to have a pulse width of 694 fs with an output power of 21.64 mW.These results demonstrate that NiTe_(2)is an effective saturable absorber material with potential applica-tions in the field of ultrafast optics.
NiTe_(2)作为一种典型的过渡金属二硫化物(TMD),具有超快的光响应、高的载流子迁移率和良好的环境稳定性,在能源、生物医学、光电子器件等领域具有广阔的应用前景。目前,有关NiTe_(2)在超快光子学中应用的研究报道很少。本文采用化学气相沉积(CVD)制备了NiTe_(2),并将其与锥形光纤相结合集成到掺铒光纤激光器(EDFL)和掺铥光纤激光器(TDFL)中获得锁模激光输出。锁模EDFL的脉冲宽度和输出功率分别为678 fs和3.92 mW。锁模TDFL的脉冲宽度估算为694 fs,输出功率为21.64 mW。这些结果表明,NiTe_(2)是一种很好的可饱和吸收材料,在超快光学领域具有潜在应用前景。
