Extraction of the species dependent dipole moment from high-order harmonic spectra in rare gas atoms
Anh-Thu Le, Toru Morishita, C. D. Lin
Based on high-order harmonic generation (HHG) spectra obtained from solving the time-dependent Schrodinger equation for atoms, we established quantitatively that the HHG yield can…
Retrieval of electron-atom scattering cross sections from laser-induced electron rescattering of atomic negative ions in intense laser fields
XiaoXin Zhou, Zhangjin Chen, Toru Morishita +2
We investigated the two-dimensional electron momentum distributions of atomic negative ions in an intense laser field by solving the time-dependent Schrodinger equation (TDSE) and…
Potential for ultrafast dynamic chemical imaging with few-cycle infrared lasers
T Morishita, A. T. Le, Z. Chen +1
We studied the photoelectron spectra generated by an intense few-cycle infrared laser pulse. By focusing on the angular distributions of the back rescattered high energy photoelect…
Analysis of two-dimensional high-energy photoelectron momentum distributions in single ionization of atoms by intense laser pulses
Zhangjin Chen, Toru Morishita, Anh-Thu Le +1
We analyzed the two-dimensional (2D) electron momentum distributions of high-energy photoelectrons of atoms in an intense laser field using the second-order strong field approximat…
Improved Lewenstein model for high-order harmonic generation of atoms and molecules with scattering wavefunctions
Anh-Thu Le, Toru Morishita, C. D. Lin
We demonstrate a simple method to improve the Lewenstein model for the description of high-order harmonic generation (HHG). It is shown that HHG spectra can be expressed as the pro…
Accurate retrieval of structural information from laser-induced photoelectron and high-harmonic spectra by few-cycle laser pulses
Toru Morishita, Anh-Thu Le, Zhangjin Chen +1
By analyzing ``exact'' theoretical results from solving the time-dependent Schrödinger equation of atoms in few-cycle laser pulses, we established the general conclusion that diffe…
