论文摘要
高强度激光器的进步开辟了强场物理学领域，并导致了广泛的技术应用。最近的X射线激光源和光学元件开发使得在X射线波长下获得极高的强度和亮度。在本文中，我们提出了一种系统设计，该设计实现了无X射线激光器的搅动脉冲扩增。具有现实实验参数的数值建模表明，接近转换限制的单秒X射线激光脉冲峰值超过1 TW，亮度超过$ 4 \ times10^{35}〜$ s $ s $ s $一贯生成。实现这种光束质量对于建立对强场X射线物理和非线性X射线光学现象的系统和定量理解至关重要。
Advances of high intensity lasers have opened up the field of strong field physics and led to a broad range of technological applications. Recent x ray laser sources and optics development makes it possible to obtain extremely high intensity and brightness at x ray wavelengths. In this paper, we present a system design that implements chirped pulse amplification for hard x ray free electron lasers. Numerical modeling with realistic experimental parameters show that near-transform-limit single-femtosecond hard x ray laser pulses with peak power exceeding 1 TW and brightness exceeding $4\times10^{35}~$s$^{-1}$mm$^{-2}$mrad$^{-2}$0.1\%bandwdith$^{-1}$ can be consistently generated. Realization of such beam qualities is essential for establishing systematic and quantitative understanding of strong field x-ray physics and nonlinear x ray optics phenomena.
