碳氢靶强激光烧蚀特性
-
摘要: 给出了准稳态情况下强激光烧蚀碳氢靶的实验结果,并与理论定标关系进行对比。 实验中采用晶体谱仪时间积分和X射线条纹相机同时获取碳氢平面靶强激光烧穿厚度和烧穿时间。采用基频光大能量注入,大焦斑(Φ 400μm),光束经列阵透镜均匀化后, 烧蚀碳氢平面靶。Abstract: The experimental results ofablation of CH targets by high power laserand the comparison with the theory have been given. The ablation thickness and timewere synchronously measured with time integrated Xray crystal spectrometers anda Xray streak camera.Using a lens arrayto make the laser energy distribution uniform, the diameter of focus spot φ400mm,Ia≈0.55×1014W/cm2,CH plane targets,m〖DD(-2
