Abstract

Nickel-vanadium (NiV)-layered double hydroxide (LDH) was fabricated into a novel saturable absorber (SA) by the liquid phase exfoliation method and utilized as the laser modulator for the first time, to our best knowledge. We investigated a passive -switched Tm:YAG ceramic laser at 2 µm with the NiV-LDH SA. Under an absorbed pump power of 7.2 W, the shortest pulse width of 398 ns was obtained with an average output power of 263 mW and a pulse repetition frequency of 101.8 kHz, corresponding to a single pulse energy at 2.30 µJ. The results indicate that the NiV-LDH SA has great research potential in the field of laser modulation.

摘要

通过液相剥离法将镍钒（NiV）层状双氢氧化物（LDH）制备成一种新型可饱和吸收体（SA），据我们所知，这是首次将其用作激光调制器。我们使用NiV-LDH可饱和吸收体对波长为2μm的被动调Q Tm:YAG陶瓷激光器进行了研究。在7.2W的吸收泵浦功率下，获得了最短脉冲宽度为398ns，平均输出功率为263mW，脉冲重复频率为101.8kHz，对应单脉冲能量为2.30μJ。结果表明，NiV-LDH可饱和吸收体在激光调制领域具有巨大的研究潜力。
