激光辐射的高谐波产生（HHG）导致了阿秒脉冲的形成，为观察和控制电子和核动力学提供了前所未有的时间分辨率。但是，阿秒脉冲的能量仍然很小，特别是光子能量超过100 eV，这限制了它们的实际应用。我们提出了一种在等离子体基x射线激光器的有效介质中放大阿秒脉冲的方法，该激光器由用于HHG的激光场的复制品装扮。建议在3.4 nm波长的类氢C5+ x射线激光中，在“水窗”范围内进行实验实现。
High-harmonic generation (HHG) of laser radiation has led to attosecond pulse formation which offers unprecedented temporal resolution in observing and controlling electron and nuclear dynamics. But the energy of attosecond pulses remains quite small, especially for photon energies exceeding 100 eV, which limits their practical applications. We propose a method for amplification of attosecond pulses in the active medium of a plasma-based x-ray laser dressed by a replica of the laser field used for HHG. The experimental implementation is suggested in hydrogenlike C5+ x-ray laser at 3.4 nm wavelength in the "water window" range.
