Abstract

In this paper, a V₂GeC saturable absorber (SA) is prepared and used to modulate a Tm:YAP laser. In continuous wave (CW) mode, an output power of 2.48 W at 1940.5 nm was achieved with a 15.39 W pump power, corresponding to an optical–optical conversion efficiency of 16.1%. Under passively Q-switched (PQS) mode, an average output power of 663 mW at 1937.4 nm was acquired with an optical–optical conversion efficiency of 4.3%, and a pulse width of 416.7 ns at 129.00 kHz was acquired in the laser stable operation, corresponding to a per pulse energy of 5.1 µJ. These experimental results demonstrate the effective modulation capabilities of the V₂GeC SA in near-infrared laser systems.

具有V₂GeC饱和吸收器的被动调q Tm:YAP激光器

本文制备了一种V2GeC饱和吸收体（SA），并将其用于调制Tm:YAP激光器。在连续波（CW）模式下，1940.5 nm处的输出功率为2.48 W，泵浦功率为15.39 W，对应于光-光转换效率为16.1%。在被动调q （PQS）模式下，在1937.4 nm处获得了663 mW的平均输出功率，光-光转换效率为4.3%，在129.00 kHz处获得了416.7 ns的脉冲宽度，对应于每脉冲能量为5.1µJ。这些实验结果证明了V2GeC SA在近红外激光系统中的有效调制能力。
