摘要

本文利用强场近似理论研究了一束强度稍弱的X射线脉冲辅助另一束强X射线脉冲作用于μ介子氢原子产生高次谐波的过程. 研究发现当弱X射线的频率为强X射线频率的一半时，可以生成超宽高次谐波频谱. 通过合成高次谐波的连续谱，得到宽度为130 zs的单个仄秒脉冲. 单个仄秒脉冲为超快变化过程的研究提供了工具.

We use the Lewenstein model to study the high harmonic generated for a μp atom exposed to two-color XUV pulses. Calculated results show a super continuum plateau in high harmonic spectrum which is formed when the time delay is 0 and XUV frequencies are 5 and 2.5. By synthesizing the continuous high harmonic spectra, a pulse as short as 130 zeptosecond is obtained. Such a single zeptosecond pulse may work as an ultrafast camera to capture ultrafast processes occurring inside nuclei.
