We demonstrated the tunable passively Q-switched Thulium-Flouride Fiber (TFF) laser based on exfoliated MoS2 saturable absorber (SA).  The generation of Q-switched pulses of the proposed experiment favors the tunable operation from 1460.0 nm to 1506.0 nm, with range of 46.0 nm. The achievable maximum repetition rate and maximum pulse energy in the experiment are 35.1 kHz and 63.2 nJ, respectively. To the best of our knowledge, the first reported tunable passively Q-switched TFF laser using exfoliated MoS2 as saturable absorber has been demonstrated.

Tantalum Selenide

A novel 2H-phase transition metal dichalcogenide (TMD)–tantalum selenide (TaSe2) with metallic bandgap structure is a potential photoelectric material. A band structure simulation of TaSe2 via ab initio method indicated its metallic property. An effective multilayered TaSe2 saturable absorber (SA) was fabricated using liquid-phase exfoliation and optically driven deposition. The prepared 2H–TaSe2 SA was successfully used for a dual-wavelength Q-switched fiber laser with the minimum pulse width of 2.95 μs and the maximum peak power of 64 W. The repetition rate of the maximum pulse energy of 89.9 kHz was at the level of 188.9 nJ. The metallic 2H–TaSe2 with satisfactory saturable absorbing capability is a promising candidate for pulsed laser applications.
