摘要 成功研制了高能炸药抽运光解碘激光器系统,实现了爆炸激光器装置的稳定激光输出,并获得了近百焦耳的激光输出能量.实验中分别测量了101.325 kPa下氩气中冲击波阵面的辐射光谱及冲击波阵面传播速度.该爆炸激光器系统利用七氟碘丙烷C3F7I作为激光工作物质,高能炸药作为抽运能源,实验中获得了较好的爆炸激光波形,激光脉宽(半峰全宽(FWHM))约34μs,最小光束发散角小于20 mrad.详细介绍了爆炸激光器的工作原理,针对具体的实验装置及实验技术路线进行了分析和描述.分别在不同实验条件下开展了相关爆炸激光实验,对实验结果进行了分析,并对影响爆炸激光输出的因素进行了分析和讨论,为进一步研制更大能量的爆炸激光装置打下了基础. A set of high explosive pumped photolytic iodine laser system was built and a steady laser output of approximate 100 J was obtained in experiments. The radiation spectra of shock wave produced by high explosive in argon of about 101. 325 kPa were measured, meantime the velocities of shock wave were also measured by photography, In the experiments, the alkyl iodine C3 F71 was used as laser working substance and a good waveform of laser was obtained. The full width at half maximum (FWHM) of laser pulse is about 34 μs and minimum angle of radiation is less than 20 mrad. The principle and technique routines were introduced in the paper. The experiments under different conditions were carried out and the expenimental results were listed and analyzed. The factors that influence the laser output had been discussed. This technique progress made it possible for making a larger energy explosive-driven iodine photodissociation laser.
