摘　　要：A novel black phosphorus （BP） solution saturable absorber （SA） is fabricated by the liquid-phase-exfoliated method and successfully used for passively Q-switched （QS） Nd：YVO4 laser. Compared with a traditional solid SA, a BP solution SA possesses more excellent optical transparency and higher damage resistance. The shortest pulse duration and highest average output power are measured to be 119 ns and 1.23 W, respectively. To the best of our knowledge, both of them are the best results among QS solid-state lasers with BP-based absorbers so far. The repetition rate is in the range of 533.2 to 722 kHz. The results indicate the potential application of the BP solution SA into high-Dower solid-state pulse lasers.A novel black phosphorus （BP） solution saturable absorber （SA） is fabricated by the liquid-phase-exfoliated method and successfully used for passively Q-switched （QS） Nd：YVO4 laser.
