Multiple collisions in crystal high-order harmonic generation
文献摘要：
We theoretically investigate high-order harmonic generation(HHG)in crystals induced by linearly polarized laser fields.We obtain the HHG spectra by solving the semiconductor Bloch equations and analyze the radiation process by different models.Here we propose a multiple collision model,in which the electrons and holes are produced at different times and places.It is found that the multiple collision trajectories can help us comprehensively and better explain the results of the quantum calculation.Moreover,we find that the harmonic suppression occurs due to the overlap of multiple collision trajectories.
