In this article, we demonstrate a laser diode pumped passively Q-switched Yb³⁺:Sc₂SiO₅ (Yb:SSO) laser for the first time, applying a graphdiyne (GDY) saturable absorber which was prepared by the liquid phase exfoliation method. Utilizing the saturable absorption characteristic of the two-dimensional GDY material, the pulsed Yb:SSO laser performances were investigated. The single pulse energy of 9.0 μJ and the peak power of 2.2 W were realized at an absorbed pump power of 3.151 W.

用于被动调Q Yb3+:Sc2SiO5 激光器的二维石墨炔

在本文中，我们首次展示了一种激光二极管泵浦被动调Q Yb ³⁺ :Sc ₂ SiO ₅ (Yb:SSO) 激光器，并应用了通过液相剥离法制备的石墨炔 (GDY) 可饱和吸收体. 利用二维GDY材料的饱和吸收特性，研究了脉冲Yb:SSO激光器的性能。在吸收泵浦功率为 3.151 W 时实现了 9.0 μJ 的单脉冲能量和 2.2 W 的峰值功率。
