本文介绍了一种用于X射线激光研究的双光束啁啾脉冲放大钕玻璃激光系统。每个光束提供20 J的输出能量，典型的脉冲持续时间为1.3 ps。可变持续时间的预脉冲是通过使用一种新的，据我们所知，光学系统产生的。由离轴抛物面反射镜和球面反射镜组成的反射光学系统，产生长6毫米、宽165微米的无色差线焦点。利用该泵浦激光系统，获得了波长为13.9nm的类镍银x射线激光。
A two-beam chirped-pulse-amplification Nd:glass laser system dedicated to x-ray laser research is described. Each beam provides an output energy of 20 J with a typical pulse duration of 1.3 ps. A prepulse of variable duration is generated by use of a novel, to our knowledge, optical system. A reflection optical system, comprised of an off-axis parabolic mirror and a spherical mirror, produces a line focus with 6-mm length and 165-microm width without chromatic aberration. By use of this pumping laser system, the nickel-like silver x-ray laser at a wavelength of 13.9 nm has been demonstrated.
