| 中文摘要 | Based on the analysis of the optical characteristic of Nd:YAG ceramic, a laser diode (LD) pumped high-efficiency high-repetition-rate acousto-optic (A-O) Q-switched miniature Nd:YAG ceramic laser was developed. Near infrared laser at 1064 nm was obtained with LD end-pumping Nd:YAG ceramic. Fused silica was adopted as A-O Q-switch crystal and the Q-switch repetition rate is adjustable from 1 Hz to 115 kHz. With a 2 W LD pumping, stable operation with pulse width of 16.4 ns peak power of 2.46 kW and energy per pulse of 40.5 mu J was achieved. At 110 kHz repetition rate, 495 mW average output power of 1064 nm was obtained, corresponding to total optical-to-optical conversion efficiency being as high as 24.75%. The experimental study about the influence of repetition rate and pumping power on the performance of A-O Q-switched pulse laser was emphasized, and the experiment results were analyzed and discussed. |
