Abstract

TaS₂ is a kind of novel metallic two-dimensional (2D) transition metal dichalcogenides (TMDs) which has broad spectral response range and fast recovery time, being pretty suitable for the application in ultrafast photonics. So far, the research on the application of TaS₂ in ultrafast photonics is rare. In this work, TaS₂ nanosheets were prepared and further a saturable absorber based on TaS₂/polyvinyl alcohol (PVA) film was fabricated. It was applied in a Yb-doped fiber laser to generate stable mode-locked pulse signals. At a pump power of 100 mW, the obtained Yb-doped mode-locked fiber laser showed a central wavelength of ∼ 1060 nm, a narrow pulse width of 573.5 ps, a repetition rate of 9.58 MHz and a maximum output power of 1.3 mW. To the best of our knowledge, this is the first time to report Yb-doped mode-locked fiber laser using TaS₂ as the saturable absorbing material.

金属TaS2：一种新发现的用于掺镱锁模光纤激光器的过渡金属

TaS2是一种新型的金属二维（2D）过渡金属二硫族化合物（TMDs），具有宽的光谱响应范围和快速的恢复时间，非常适合在超快光子学中的应用。目前，对TaS2在超快光子学中的应用研究尚不多见。本文制备了TaS2纳米片，并进一步制备了基于TaS2/聚乙烯醇（PVA）薄膜的可饱和吸收体。将其应用于掺镱光纤激光器中，产生稳定的锁模脉冲信号。在泵浦功率为100 mW时，获得的掺镱锁模光纤激光器的中心波长为~ 1060 nm，窄脉宽为573.5 ps，重复频率为9.58 MHz，最大输出功率为1.3 mW。据我们所知，这是第一次报道使用TaS2作为可饱和吸收材料的掺镱锁模光纤激光器。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
