Abstract
The monolayer WSe2 material was utilized for a saturable absorber to create a 2.7 μm passively Q-switched pulse laser. The maximal single pulse energy was 2.75 µJ, and the highest peak power was measured approximately 2.53 W. As far as we know, this is the first instance of monolayer WSe2 being used for passive Q-switching operation in mid-infrared. The results provide favorable evidence for monolayer WSe2 as a mid-infrared Q-switcher and show the promise of monolayer two-dimensional materials for ultrafast pulsed laser applications.
