论文摘要
在激光辅助XUV电离中研究了激光脉冲的磁场效应。通过数值求解三维时间依赖性的Schrödinger方程，我们发现光电子动量分布被IR条纹场的磁场效应扭曲。它导致横向摩托和时间依赖的纵向光电子动量移位，通过使用非硅矫正的强场近似，可以在分析上进一步证实。我们还证明，磁场不会影响从条纹频谱中检索到的时间移，尽管磁场效应引起的动量偏移显然会改变条纹频谱。我们的工作揭示了通过Attsend Streaking Technique的激光脉冲的时间分辨的北极质效应。
The magnetic-field effect of the laser pulse is investigated in laser-assisted XUV ionization. By numerically solving the three-dimensional time-dependent Schrödinger equation, we find that the photoelectron momentum distribution is distorted by the magnetic-field effect of the IR streaking field. It results in a transverse-momentum- and time-delay-dependent longitudinal photoelectron momentum shift, which is further analytically confirmed by employing the nondipole corrected strong field approximation. We also demonstrate that the magnetic field does not affect the time shift retrieved from the streaking spectrum, although the streaking spectrum is apparently altered by the momentum shift induced by the magnetic-field effect. Our work reveals the time-resolved nondipole effect of the laser pulse by the attosecond streaking technique.
