摘要：
We proposed a passively stabilized Q-switched Er : Lu2O3 laser at 2845 nm, applying a MXene Nb2CTx nanosheets saturable absorber prepared by the liquid-phase exfoliation method. The surface morphology and nonlinear properties of this nanosheet were systematically characterized. Average output power of 542 mW for the Q-switched laser was obtained under 7.26 W of absorbed pump power. Meanwhile, the Q-switched pulse duration was measured to be 223.7 ns with 142.9 kHz repetition rate corresponding to a peak power of 16.96W. (C) 2021 Optical Society of America
