All-solid-state Tm lasers have a wider wavelength range and higher output power compared to other types of lasers. In this work, we demonstrate an all-solid-state, high repetition, Tm:YAP laser Q-switched by a graphdiyne (GDY) saturable absorber. The high-quality optical nonlinear material GDY, synthesized by a cross-coupling method, exhibits a strong nonlinear optical response. The application of GDY as a saturable absorber in the passively Q-switched (PQS) Tm:YAP of an all-solid-state laser has been realized with the shortest pulse duration of ~785 ns and repetition frequency of ~199.6 kHz at a central wavelength of 1985.8 nm. This represents the shortest pulse duration and the highest repetition frequency achieved from GDY in a solid-state Tm laser to date. Our work demonstrates the remarkable nonlinear optical properties of GDY, which holds promising potential in the field of optoelectronics.
与其他类型的激光器相比，全固态Tm激光器具有更宽的波长范围和更高的输出功率。在这项工作中，我们展示了一种由石墨炔（GDY）可饱和吸收体调Q的全固态、高重复频率Tm:YAP激光器。通过交叉耦合方法合成的高质量光学非线性材料GDY表现出强烈的非线性光学响应。在中心波长为1985.8nm的全固态激光器的被动调Q（PQS）Tm:YAP中，已实现将GDY用作可饱和吸收体，其最短脉冲持续时间约为785ns，重复频率约为199.6kHz。这代表了迄今为止在固态Tm激光器中GDY实现的最短脉冲持续时间和最高重复频率。我们的工作证明了GDY具有卓越的非线性光学特性，在光电子领域具有广阔的应用前景。
