We demonstrate a Q-switched Thulium-doped fiber laser (TDFL) operating at 1941 nm region based on multi-layer black phosphorous (BP) as a saturable absorber (SA). The BP-based SA was prepared by mechanically exfoliating BP crystal and fixing the acquired BP flakes onto the scotch tape. A small piece...
