实验证明，用持续475 fs的高强度激光脉冲纵向抽运2 mm长的钼预成型等离子体，可产生波长为18.9 nm的高定向软x射线激光。光束的散度被评估为亚毫弧度量级，并且只需要150兆焦耳的泵浦激光能量。
We experimentally demonstrate that by longitudinally pumping 2 mm long molybdenum preformed plasma with high-intensity 475 fs duration laser pulse, a highly directive soft-x-ray laser at 18.9 nm wavelength is generated. The divergence of the beam is evaluated to be of the submilliradian order, and only requires a pump laser energy of 150 mJ.
