摘要
利用针孔透射光栅光谱仪(PTGS)研究了波长为1.06μm、平均功率密度为2×10^(12)W/cm^2的线聚焦激光照射Al平板靶所产生的线状等离子体的轴向和非轴向X射线发射(5—200A)的光谱和空间分布特性。文中也就该条件下的线状等离子体作为X射线激光增益介质的有关问题进行了讨论。
The spectral and spatial characteristics of X-ray emission (5-200A) along or off the axis of the plasma column, produced by 1.06 μm laser beam irradiating luminum flat target in line focused configurations with an average power density 2×10^(12)W/cm^2, are studied by using a pinhole transmission grating spectrograph (PTGS). Problems for the plasma as an X-ray-laser gain medium are also discussed.
