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.

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.
