摘要

本文报道了一种被动调q 2 μm Tm:YAP固体激光器，该激光器采用MoS2/CuO异质结作为可饱和吸收体。在入射泵浦功率为18.12 W时，脉冲重复率最高，脉冲宽度最短，单脉冲能量最大，脉冲峰值功率最高，分别为63.57 kHz、835 ns、19.19 μJ和22.98 W。实验结果表明，MoS2/CuO异质结是高性能近红外脉冲激光器的优良饱和吸收材料。

Passively Q-switched Tm:YAP laser based on MoS2/CuO heterojunction saturable absorber

In this paper, we report on a passively Q-switched 2 μm Tm:YAP solid-state laser using the MoS₂/CuO heterojunction as the saturable absorber. At an incident pump power of 18.12 W, the highest pulse repetition rate, shortest pulse width, largest single pulse energy, and highest peak power were obtained as 63.57 kHz, 835 ns, 19.19 μJ and 22.98 W, respectively. The experimental results indicate that MoS₂/CuO heterojunction is an excellent saturable absorber for high-performance near-infrared pulsed lasers.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
