摘要

Black phosphorus (BP) saturable absorber (SA) solution is fabricated by liquid-phase exfoliation method. By using the BP-SA solution, a compact diode-pumped passively Q-switched Nd:YAG and Nd:YVO4 laser has been demonstrated. 100 Hz and 1 kHz repetition rate pulse lasers are achieved, respectively. The minimum pulse duration is 3.56 ns. In the Q-switched Nd:YVO4 laser with wideband absorbers, the lowest repetition rate and the shortest pulse duration are obtained for the first time to the best of our knowledge. The maximum single pulse energy is as much as 0.1 mJ. Our results show that BP-SA solution can be developed as an effective SA to achieve nanosecond pulse laser.
