摘要：
A dual-loss Q-switched laser was realized by applying a home-made 2.5 nm thick WTe2 to an acousto-optic modulated laser. Besides conventional pulse compression, the inclusion of WTe2 could obviously improve the average output power by 29.6% and reduce the laser threshold by 20%, even with the introduced 8% nonsaturable loss. The average output-power improvement and pulse compression in this dual-loss modulated laser resulted in a 113.7% increase of peak power. According to the measured spectra of the laser and the photoluminescence of WTe2, the laser-induced excitonic light emission may be the reason for this laser's gain. © 2020 The Japan Society of Applied Physics.
