Abstract

In recent years, the diversity of transition metal dichalcogenides (TMDs) have made them widely used in fiber lasers for the saturable absorption effect. Zirconium ditelluride (ZrTe₂), as a member of TMDs, has a high anti-damage threshold, and it exhibits excellent and controllable photoelectric performance due to the anisotropy of the band structure. In this paper, we prepared a ZrTe₂ saturable absorber film for passively mode-locking operation in an erbium-doped fiber laser and obtained an optical pulse output with a central wavelength of 1564.4 nm and a repetition frequency of 5.81 MHz. The spectral 3-dB bandwidth is 0.51 nm, the pulse width is 2.98 ps, and the signal-to-noise ratio of the fundamental frequency is 60 dB. These results show the potential of ZrTe₂ as a new saturable absorber material for generating ultrashort pulses, and this is the first demonstration for mode-locked fiber lasers based on ZrTe₂ material.
