摘要：
The saturable absorption properties of few-layer graphitic carbon nitride (g-C3N4) nanosheets near 3 mu m were investigated. A stable Q-switched Er:Lu2O3 laser at 2.84 mu m was realized by using a home-made g-C3N4 saturable absorber (SA), generating a pulse duration of 351 ns and an average output power of 1.09 W at a repetition rate of 99 kHz, corresponding to a pulse energy of 11.1 mu J. Our result indicates a great potential of g-C3N4 as a new SA in the 3 mu m wavelength range. (C) 2017 Optical Society of America
