The saturable absorption properties of few-layer graphitic carbon nitride (g-CN) nanosheets near 3 μm were investigated. A stable Q-switched Er:LuO laser at 2.84 μm was realized by using a home-made g-CN 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-CN as a new SA in the 3 μm wavelength range.
研究了少层石墨相氮化碳（g-CN）纳米片在3μm附近的饱和吸收特性。通过使用自制的g-CN饱和吸收体（SA），实现了波长为2.84μm的稳定调Q掺铒：镥氧激光器，脉冲持续时间为351ns，重复频率为99kHz时平均输出功率为1.09W，对应脉冲能量为11.1μJ。我们的结果表明g-CN作为3μm波长范围内新型饱和吸收体具有巨大潜力。
