Abstract

Synopsis: We calculate the low-order harmonic generation (LOHG) by solving three-dimensional time-dependent Schrödinger equation with an accurate model potential of helium (He) atom in an intense laser fields. The satellite-peak structures of the LOHG are obtained in the harmonic spectra of He atom. We analyze the emission properties of the LOHG by employing a synchrosqueezing transform technique. Our results show that the satellite-peak structures contain the information of the bound states and the Stark shift of He atom in an intense laser fields.
