Universal saturable absorbers covering wavelengths from near-infrared to mid-infrared bands have attracted widespread interest. In this contribution, we experimentally demonstrated the broadband saturable absorption of multilayer black phosphorus from 1 μm to 2.7 μm wavelengths. With liquid-phase-exfoliated black phosphorus nanoflakes as the saturable absorber, the Q-switching operation of bulk lasers at 1.03 μm, 1.93 μm, and 2.72 μm was realized, respectively. This work will open up promising optoelectronic applications of black phosphorus for the mid-infrared spectral region.
