中文摘要	研制了激光二极管(LD)抽运的高效高重复频率声光调QNd∶YAG陶瓷微型激光器件。激光器采用激光二极管纵向同轴抽运Nd∶YAG陶瓷得到1064nm近红外激光输出,采用熔融石英作声光介质,声光调Q重复频率1Hz～115kHz可调。使用2W的激光二极管抽运,获得脉冲宽度16.4ns,峰值功率2.46kW,单脉冲能量40.5μJ的稳定运转。在重复频率110kHz时获得495mW的平均功率,总光光转换效率达24.75%。研究了重复频率及抽运功率对声光调Q脉冲激光器性能的影响,并对实验结果进行了相应的分析讨论,在理论上加以合理的解释。; 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 2W LD pumping, stable operation with pulse width of 16.4 ns peak power of 2.46 kW and energy per pulse of 40.5 μJ, 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.; 国家自然科学基金重点项目(50132010))资助项目
