Ultrafast laser soliton mode-locked at 1.5 mu m region based on Cr2AlC MAX phase as a saturable absorber

In this experiment, a passively mode-locked erbium-doped fiber laser was successfully realized by utilizing chromium aluminum carbide (Cr2AlC) MAX phase as a saturable absorber (SA). The Cr2AlC MAX phase was fabricated by casting method with polyvinyl alcohol to compose a thin film. By a 203-m cavit...
