摘要
利用小型脉冲YAG激光器在能量100~300 MDI范围内成功驱动了5.5 μm厚度,直径0.5~0.8 mm铝飞片,最高速度达到6.6 km/s.详细介绍了激光驱动飞片的过程、实验方法和测试系统等,并对实验回收的样品进行了分析,结果显示飞片具有较好的平面性、完整性和重复性.利用Gurney理论和Lawrence模型对激光驱动飞片的过程进行了解析分析,理论结果与实验值吻合得较好.
Abstract
The aluminum flyers with 5.5 μm thickness and 0.5~0.8 mm diameter have been driven successfully by mini size YAG laser in the energy range of 100~300 mJ. The average velocities of flyer were up to 6.6 km/s, and the relationship between flyer velocities and energy density has been obtained in experiments. The analysis to the recovery samples showed that the flyers have good figure during the process of flying. The whole process can be simutate by using Gurney theory and Lawrence model and the academic results are in good accord with the experimental results.
