In this paper, we report 4 different saturable absorbers based on 4 transition metal
dichalcogenides (MoS_2, MoSe_2, WS_2, WSe_2) and utilize them to Q-switch a ring-cavity …

Due to the unique properties of two-dimensional (2D) materials, much attention has been
paid to the exploration and application of 2D materials. In this review, we focus on the …

Compared with continuous wave lasers, ultrafast lasers have the advantages of ultra-short
pulse width and ultra-high peak power, and have significant applications in optical …

We demonstrate a ytterbium (Yb) and an erbium (Er)-doped fiber laser Q-switched by a
solution processed, optically uniform, few-layer tungsten disulfide saturable absorber (WS2 …

As one of the greatest inventions in the 20th century, ultrafast lasers have offered new
opportunities in the areas of basic scientific research and industrial manufacturing. Optical …

We investigated nonlinear optical characteristics of Tungsten disulfide (WS 2) films and
experimentally demonstrated their high potential for application as nonlinear saturable …

We propose two schemes for achieving tungsten disulfide (WS 2)-based saturable absorber
(SA) and saturable absorber mirror (SAM). By utilizing the pulsed laser deposition method …

We demonstrate the passive Q-switching operation of an erbium-doped fiber laser using a
few-layer WS 2-based saturable absorber with evanescent field interaction. WS 2 flakes …

Fiber lasers consist of optical fibers as gain medium in which their core is doped with rare
earth elements such as erbium, ytterbium and thulium. In those early years, ultrashort fiber …
