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…
Suppression of molecular decay in ultracold gases without Fermi statistics
J. P. D'Incao, B. D. Esry
We study inelastic processes for ultracold three-body systems in which only one interaction is resonant. We have found that the decay rates for weakly bound molecules due to collis…
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…
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…
