Black phosphorus as saturable absorber for the Q-switched Er:ZBLAN fiber laser at 2.8 μm.
TL;DR: To the best of the knowledge, this is the first time that black phosphorus can realize Q-switching of 2.8-μm fiber laser and the research results show thatblack phosphorus is a promising saturable absorber for mid-infrared pulsed lasers.
Journal ArticleDOI

W. D. Tan,Ching Yuan Su,Randall J. Knize,Randall J. Knize,Guoqiang Xie,Lain-Jong Li,Dingyuan Tang +6 more
TL;DR: In this article, the mode-locking of a ceramic Nd:yttrium aluminum garnet (YAG) solid-state laser (SSL) with solution processed graphene as saturable absorber (SA) was demonstrated.
Journal ArticleDOI
Black phosphorus as saturable absorber for the Q-switched Er:ZBLAN fiber laser at 2.8 {\mu}m
TL;DR: In this paper, a passively Q-switched Er-doped ZBLAN fiber laser at the wavelength of 2.8 µm was demonstrated, achieving a maximum average power of 485 mW with corresponding pulse energy of 7.7 µm and pulse width of 1.18 µm at repetition rate of 63 kHz.
Journal ArticleDOI
Mid-infrared mode-locked pulse generation with multilayer black phosphorus as saturable absorber.
TL;DR: The results demonstrate the feasibility of black phosphorus flake as a new two-dimensional material for application in mid-infrared ultrafast photonics.
Journal ArticleDOI
