成功制备了少层石墨二炔（GDY），并将其用作可饱和吸收体，以产生瓦特级超快固态体激光器。使用 Nd:YVO4 晶体作为增益介质，脉冲宽度为 23 ps，重复频率为 92.9 MHz，获得了高达 1.27 W 的最大输出功率。据我们所知，这是 GDY 作为锁模器在全固态体激光器中的首次应用。这些结果表明 GDY 在生产高功率超快激光器方面具有广阔的潜力。 (C) 2020 年美国光学学会
Few-layered graphdiyne (GDY) was successfully fabricated and applied as a saturable absorber to generate a watt-level ultrafast solid-state bulk laser. The maximum output power of up to 1.27 W was obtained with a pulse width of 23 ps and a repetition rate of 92.9 MHz, using Nd:YVO4 crystal as a gain medium. To the best of our knowledge, this is the first application of GDY as a mode locker in all-solid-state bulk lasers. These results indicate the promising potential of GDY for producing high-power ultrafast lasers. (C) 2020 Optical Society of America
