Abstract

An all-normal dispersion passively mode-locked Yb-doped fiber laser with a Bi₂Te₃ absorber is presented. The modulation depth of this kind of saturable absorber was measured to be 8.4%. By incorporating a Bi₂Te₃/PVA film into a Yb-doped fiber laser oscillator, a mode-locked fiber laser oscillator was achieved. The repetition rate and the central wavelength are 25.6 MHz and 1052.7 nm, respectively. The 3-dB spectral width is 0.45 nm and the pulse duration is 417 ps. The results indicate that topological insulator Bi₂Te₃ possesses the potential for ultrafast fiber laser application.
