摘要:Based on a high-quality WSe 2 film prepared by the ultrasound-assisted liquid phase exfoliation (UALPE) method, a passively Q-switched all-solid-state Tm:YLF laser at 2 μm with high peak power was presented. The laser characteristics versus the pump power were investigated experimentally. Under the pump power of 8.84 W, the maximum single pulse energy of 12.8 μJ and peak power of 30 W were obtained, corresponding to the perfect pulse duration and maximum repetition rate of 427 ns and 82 kHz, respectively. To the best of our knowledge, it is the first presentation of WSe 2 -SA employed in a solid-state Q-switched crystalline laser at 2 μm. © 2018 Elsevier Ltd
