Deskripsi
Bi2O2Se holds potential for the realization of 2D optical modulators due to its broadband nonlinear response, air stability and carrier mobility. Here, the authors report the realization of defect-engineered Bi2O2Se nanoplates as saturable absorbers for femtosecond solid-state lasers, showing improved output power and pulse duration.
