Using a home-made black phosphorus plate (BPP) as handedness controller and Qswitch modulator synchronously, a similar to 1.6 mu m pulsed vortex laser with well-determined handedness is demonstrated in this letter. Stable vortex pulses of LG(0, + 1), LG(0,-1,) LG(0, + 2) and LG(0,-2) modes were respectively achieved from compact resonant cavities in this experiment. Such pulsed vortex laser should have promising applications in various fields based on its simple structure, controllable handedness, and carried orbital angular momentum.
