摘要

这项研究将基于 V2AlC 的可饱和吸收体（SA）应用于 2 μm 波段的被动模式锁定（PML）激光器。通过 I-scan 方法检测了基于 V2AlC 的可饱和吸收体的饱和强度和调制深度，分别为 225.05 MW/cm2 和 7.68%。在 PML 模式下，Tm:YAP 激光器在 1939 nm 波长处获得了 2.12 W 的平均功率，在 82.49 MHz 波长处获得了 1077 ps 的脉冲宽度。此外，该激光器还表现出良好的光束质量因子（M2），测量结果小于 1.2。这些结果将为基于 V2AlC 的 SA 在超快激光器中的应用铺平道路。

Passively mode-locked Tm:YAP laser with a V2AlC saturable absorber

In this work, a V₂AlC-based saturable absorber (SA) was applied to a 2 μm band passively mode-locked (PML) laser. The saturation intensity and modulation depth of the V₂AlC-based SA were detected by the I-scan method, which were 225.05 MW/cm² and 7.68%, respectively. In the PML mode, an average power of 2.12 W at 1939 nm and a pulse width of 1077 ps at 82.49 MHz were obtained from the Tm:YAP laser. In addition, the laser exhibited a good beam quality factor (M²) which was measured to be less than 1.2. These results will pave the way for the application of V₂AlC-based SA in ultrafast lasers.
