The acousto-optical Q-switched Nd:GGG laser

摘要

In this article, we demonstrated the acousto-optical Q-switching performance of a high-power diode-pumped Nd:GGG laser. The maximum average output power of 2.56 W was obtained at the repetition rate of 15 kHz, and the minimum pulse width of 21 ns was obtained under the pump power of 9.18W, the peak power and the pulse energy were calculated to be 11.4 kW and 253.6 μJ. The conversion efficiency of the output power from CW to Q-switching operation was amounted to 60.8%.
