title: Graphitic C3N4as a new saturable absorber for the mid-infrared spectral range.
abstract: The saturable absorption properties of few-layer graphitic carbon nitride (g-C3N4) nanosheets near 3 μm were investigated. A stable Q-switched Er:Lu2O3laser at 2.84 μm was realized by using a home-made g-C3N4saturable 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-C3N4as a new SA in the 3 μm wavelength range.
