摘要
对激光二极管(LD)抽运无机液体体系在流动状态下进行了激光实验研究, 初步实现了流动状态下较长时间和较高重复频率的激光脉冲输出, 最大单脉冲能量为5 mJ, 最高抽运频率为400 Hz。根据实验参数数值计算了激光脉冲能量, 初步分析了抽运频率、流场特性和环境湿度对激光输出性能的影响, 为进一步开展无机液体流动激光实验积累了经验。实验结果表明, LD抽运的无机液体体系在流动时能有效地避免热沉积, 可以获得较长时间和较高频率的激光脉冲输出, 而流场特性和环境湿度对激光输出具有十分重要的影响, 需要优化设计流道和控制环境湿度。
Abstract
Lasing experiment of inorganic liquid system pumped with laser diode under flowing status is carried out, high repeat frequency laser pulse output is achieved in long time, the maximum single laser pulse energy is 5 mJ and the maximum pumping frequency is 400 Hz. The laser pulse energy is simulated according to the experiment parameters, and the influence of pumping frequency, flowing parameter and environment humidity to the laser output capability are analyzed initially. The experiment results show that the inorganic liquid laser system pumped with laser diode can avoid heat deposition effectively under flowing status and obtain high repeat frequency laser pulse output in long time; the flowing parameter and environment humidity possess very important influence to the laser output, it is very necessary to design the conduit structure excellently and control the environment humidity.
