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…
Trapping of Neutral Mercury Atoms and Prospects for Optical Lattice Clocks
H. Hachisu, K. Miyagishi, S. G. Porsev +5
We report a vapor-cell magneto-optical trapping of Hg isotopes on the intercombination transition. Six abundant isotopes, including four bosons and two fermions,…
Quantum path interference in the wavelength dependence of high-harmonic generation
K. Schiessl, K. L. Ishikawa, E. Persson +1
We investigate the dependence of the intensity of radiation due to high-harmonic generation (HHG) as a function of the wavelength of the fundamental driver field. Superimposed on a…
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…
Two-color photoassociation spectroscopy of ytterbium atoms and the precise determinations of s-wave scattering lengths
Masaaki Kitagawa, Katsunari Enomoto, Kentaro Kasa +4
By performing high-resolution two-color photoassociation spectroscopy, we have successfully determined the binding energies of several of the last bound states of the homonuclear d…
