ReSe2 as a saturable absorber in a Tm-doped yttrium lithium fluoride (Tm:YLF) pulse laser
Abstract
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.
