Abstract

Metal-organic framework (MOF) is an emergent material that consists of metal ions and highly porous organic ligands. In this study, we demonstrate a 2 μm all-fibre mode-locked thulium/holmium-doped fiber laser (THDFL) by utilizing a nickel-based MOF (Ni-MOF) as a saturable absorber (SA) material. For the fabrication of the SA, the material was drop-casted on an arc-shaped fiber. The SA showed a 19.98 MW/cm² saturation intensity and an exceptionally high modulation depth of 15.3 %, surpassing previously reported materials in this wavelength range. The laser output centered at 1907.66 nm with an average power reaching up to 2.057 mW. The fundamental pulse rate and width were 14.30 MHz and 1.664 ps, respectively. Consequently, the THDFL generates pulses with an energy of 175 pJ and a peak power of 105 W. Mode-locked operation proved stable as the laser was observed over 2 h and showed a signal-to-noise ratio (SNR) of about 48 dB. Notably, this work represents the first demonstration of Ni-MOF as an SA in a THDFL, opening new avenues for ultrafast fiber laser development.

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.
