| Tóm tắt | I will review recent progress in understanding nonlinear processes in intense laser-matter interaction. As an atom or molecule is placed in a intense laser field, a valence electron can be tunneled out into the continuum. As the laser field changes its direction, this electron has a chance to come back and interact with the parent ion. This recollision is at heart of various nonlinear processes such as high-order harmonic generation (HHG), high-energy above-threshold ionization (HATI), non-sequential double ionization (NSDI). Those nonlinear processes contain information about the target, and therefore can serve as tools for self-imaging of target structure. However, it remains a great challenge to disentangle the target structure information from the experimental measurements, especially for fast evolving dynamically systems. Finally I will discuss the implication for future research in this field in Vietnam.
