We demonstrated that gold nanobipyramids (Au-NBPs) can be used as saturable absorbers for ultrafast pulsed-laser application, for the first time. Au-NBPs are prepared through a seed-mediated growth method, and performance is investigated in a passively Q-switched Nd:YVO4 laser. In the Q-switched operation the maximum average output power that can be achieved is 151 mW. The minimum pulse width is 396 ns at a pulse repetition rate of 90.6 kHz.
我们首次证明了金纳米双锥体（Au-NBPs）可作为超快脉冲激光应用的可饱和吸收体。Au-NBPs通过种子介导生长法制备，并在被动调Q Nd:YVO4激光器中研究其性能。在调Q操作中，可实现的最大平均输出功率为151 mW。在脉冲重复频率为90.6 kHz时，最小脉冲宽度为396 ns。
