被动调Q高功率脉冲串激光器

摘要

The article reports a high power burst laser for laser range-finder application. It uses the technology of passive Q-switch with crystal of Cr4+: YAG, in order to achieve the steady burst pulses. With the suitable design of the YAC crystal and the cavity,it can achieve the energy of 800 mJ when the pulse frequency is 10 Hz,it also gives good beam quality. Using the software of CF design to analyze the cooling liquid, it optimizes the design of the structure and enhances the suitability and the credibility of the LASER for possible environment.%介绍了一种以激光测距机为主要应用背景的高功率脉冲串激光器,该激光器在设计上采用了紧包浸反射聚光腔单只氙灯泵浦Nd:YAG,应用了Cr4+:YAG晶体被动调Q技术,实现了稳定的脉冲串方式工作状态,在10 Hz频率下,脉冲串输出能量大于800mJ.利用有限元分析软件分析了冷却液流路,改进了聚光腔端盖结构设计,提高了激光器的环境适应性及器件可靠性.
