使用单壁碳纳米管 (SWCNT) 作为可饱和吸收器 (SA) 演示了在 1073 nm 区域运行的稳定无源 Q 开关掺镱光纤激光器 (YDFL)。 SA 使用聚乙烯醇 (PVA) 作为主体聚合物制备，并通过将 SWCNT/PVA 薄膜夹在两个光纤连接器之间来集成到 YDFL 环形腔中。在 95.4 mW 阈值 980 nm 泵浦功率下，可实现稳定的脉冲序列，重复频率为 17.1 kHz，脉冲宽度为 6.45 s，脉冲能量为 3.1 nJ。随着泵浦功率增加到 117.5 mW，脉冲串重复率也增加到 23.6 kHz。在最大泵浦功率 117.5 mW 时实现了 3.11 s 的最短脉冲宽度和 4.4 nJ 的脉冲能量 (c) 2014 Wiley periodicals, Inc.

A stable passive Q-switched Ytterbium-doped fiber laser (YDFL) operating at 1073-nm region is demonstrated using single-walled carbon-nanotubes (SWCNTs) as a saturable absorber (SA). The SA is prepared using polyvinyl alcohol (PVA) as a host polymer and integrated in the YDFL ring cavity by sandwiching the SWCNT/PVA thin film between two fiber connectors. A stable pulse train is achieved with 17.1-kHz repetition rate, 6.45-s pulse width, and 3.1-nJ pulse energy at the threshold 980-nm pump power of 95.4 mW. As the pump power increases to 117.5 mW, the pulse train repetition rate also rises to 23.6 kHz. The shortest pulse width of 3.11 s and pulse energy of 4.4 nJ are achieved at the maximum pump power of 117.5 mW (c) 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1770-1773, 2014
