摘要
本工作测量了类氖锗3s-3pX射线激光的23.2nm和23.6nm两条强激光跃迁线水平方向和垂直方向的空间分布,当靶长20mm时,X射线激光水平方向束发散角约为12mrad,主束指向偏离线状等离子体轴线约8mrad;垂直方向束发散角约为22mrad,本工作还采用钼/硅多层膜平面反射镜,对X射线激光进行正反射,获得了X射线激光双程放大的光学特性。
The spatial profiles in the horizontal and vertical direction of lasing line intensity of neon-like germanium were measured. For a 20mm long plasma of 102uuuuuum lateral dimension, the main beam in the horizontal direction is found to exhibit an angular divergence of 12 mrad with a offset displaced 8 mrad from the plasma axis and the beam angular divergence in vertical direction is about 22 mrad. In addition, the characteristic of beam optics of the double-pass amplification was diagnosted using a Mo/Si multilayer mirror.
