Synchronous Pumped A-O Q-switched All Solid Pulse Laser

本文首次提出了同步泵浦声光调Q全固态脉冲激光器,分析了其基本理论,设计并实现了这种新型激光器。它克服了现有小型全固态脉冲激光器存在寄生多脉冲和峰值功率还不够高的缺点,用2W LD的泵浦时,得到了重复频率为4.5 kHz、峰值功率为6 kW、脉宽为18 ns、无寄生脉冲的连续脉冲激光输出,可以较好地满足激光测距和激光雷达对此类激光器性能的要求。本文对实验方案、设备和结果进行了详细的描述。

The article puts forward the synchronous pump A-O Q-switched all solid-state pulse laser, analyzes the basic theory of it, designs and realizes this new type of pulse laser. The laser overcomes the faults of the parasitical laser pulse which exists now small all solid-state pulse laser and low power of laser pulse peak value. We have got the continuous output laser pulse without parasitical pulse, which is with the repeat frequency 4.5 kHz, the peak power value 6 kW, and the width of pulse 18 ns, by using 2 W LD pump. The laser, with higher peak power value and better laser pulse, can meet the demand of laser rangefinder and laser radar. The article describes in detail the experiment scheme, experiment device and experiment results.
