Abstract
Passive Q-switched Erbium-doped fiber laser (EDFL) and Ytterbium-doped fiber laser (YDFL) incorporating black phosphorus (BP) tape as saturable absorber is proposed and practically demonstrated. A clean tape is used to mechanically exfoliate few layers BP from 99.995% purity BP crystal. The BP tape is cut into a small piece and sandwiched between two standard FC/PC fiber ferrule end surfaces with index matching gel. Q-switching operation of EDFL and YDFL is occurred between pump power range of 35.7 mW to 115.5 mW and 115.2 mW to 188.0 mW respectively..
