Ultrashort Pulse Generation With a Black Phosphorus Thin Film Absorber

This paper presents a mode-locked fiber laser incorporating a black phosphorus (BP) thin film as a saturable absorber (SA), with polyvinyl alcohol (PVA) serving as the host material for BP compound integration in the thin film fabrication. The fiber laser's resonant cavity spans a total length...
