摘要：

In this paper, a Q-switched and three-color operation of Neodymium-doped silica all-fiber laser is realized, in which, a few-layer transition metal dichalcogenides WS2 is pioneered to be used as a saturable absorber (SA). The compact and simple linear cavity contains homemade fiber mirrors by directly depositing a multilayer coating the SiO2/Ta2O5 dielectric films on fiber end-face. In particular, by inserting the WS2-SA into the FP laser cavity, it is found that a stable Q-switching operation was achieved with the higher signal-to-noise ratios (SNR) of 60.76 dB, and the shortest pulse duration of 990 ns, as well as the maximum repetition rate of 124.4 kHz. Meanwhile, the maximum average output power and maximum pulse energy are close to 8.9 mW and 71.5 nJ, respectively. This is, the first demonstration of compact WS2-based neodymium-doped all-fiber laser operation at 1081.9, 1091.3 and 1100.1 nm.
