In our work, a InSe-PVA film-type modulator was successfully prepared. Its nonlinear optical properties were investigated and its application for obtaining large-energy mode-locked Er-doped fiber laser also demonstrated. Stable operation with maximum pulse energy of 20.4 nJ at repetition rate 586.3 kHz generated. The average output power 11.96 mW under the pump 560 mW. Our findings suggest that InSe has competitive performance in acting as ultra-fast comparison commonly used two-dimensional materials. addition, experiment demonstration will provide useful guidance future investigations operations applications InSe-based devices.
