摘要

This study investigates the applicability of a few-layer structure ReSe2 as a saturable absorber (SA) for demonstrating a passively Q-switched pulse laser.The ReSe2 SA had a modulation depth of 6.86％.The Q-switched experiment was successful in delivering a maximum average output power of 180 mW at the wavelength of 1906.5 nm.The optimal pulse train had a pulse width of 1.61 μs and a repetition rate of 28.78 kHz.The experiment results verify that the few-layer structure ReSe2 could behave as an excellent SA at all-solid-state lasers,increasing the selection of SAs at near 2 μm lasers.
