Summary : When atoms or molecules are exposed to intense laser fields, they emit coherent soft-x-ray radiation called high harmonics during the strong-field photo-ionization process. The underlying mechanism of high harmonic generation is now well understood with the framework of the strong field approximation (SFA). The SFA is based on the quantum treatment of single electron motion in the continuum in the presence of a strong laser field. I will show how the SFA framework can be used to measure attosecond optical pulses and to snapshot the image of spatial structures/dynamics of bound state electrons inside molecules.
