Abstract
The saturable absorption properties of few-layer graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) nanosheets near 3 μm were investigated. A stable Q-switched Er:Lu<sub>2</sub>O<sub>3</sub> laser at 2.84 μm was realized by using a home-made g-C<sub>3</sub>N<sub>4</sub> 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 μJ. Our result indicates a great potential of g-C<sub>3</sub>N<sub>4</sub> as a new SA in the 3 μm wavelength range.Entities:
