二维NiTe2制备及其在1.5/2 μm锁模光纤激光器中的应用
Preparation of Two-dimensional NiTe2 and Its Application in 1.5/2 μm Mode-locked Fiber Lasers
摘要
Abstract
As a representative transition metal dichalcogenides(TMD),NiTe2 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 NiTe2 in the field of ultrafast photonics.In this work,NiTe2 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 NiTe2 is an effective saturable absorber material with potential applica-tions in the field of ultrafast optics.关键词
