Two-dimensional ReS_2 nanosheets based saturable absorbers for passively mode-locked fiber lasers

摘要

We prepared ReS_2 nanosheets by liquid-phase exfoliation and fabricated ReS_2 saturable absorbers with all-fiber integrated structure. Their nonlinear optical properties were investigated systematically. The results demonstrate that ReS_2 nanosheets owns excellent nonlinear saturable absorption properties.
