Atomically thin Bi<sub>2</sub>O<sub>2</sub>Se has emerged as a novel two-dimensional (2D) material with an ultrabroadband nonlinear optical response, high carrier mobility and excellent air stability, showing great potential for the realization of optical modulators. Here, we demonstrate a femtosecond solid-state laser at 1.0 µm with Bi<sub>2</sub>O<sub>2</sub>Se nanoplates as a saturable absorber (SA). Upon further defect regulation in 2D Bi<sub>2</sub>O<sub>2</sub>Se, the average power of the ...[more]
