Optical dipole force on ladder-like three-level atomic systems driven by chirped few-cycle-pulse laser fields
Optical dipole force ladder-like three-level atomic systems chirped few-cycle-pulse laser fields Optics
2012/5/17
We report a study on the optical dipole force in a ladder like three level atomic systems in the context of coherent population transfer with the chirped few-cycle-pulse laser fields. The phenomenon o...
Relativistic quantum theory of high harmonic generation on atoms/ions by strong laser fields

2011/9/1
High-order harmonic generation (HHG) by hydrogenlike atoms/ions in the uniform periodic electric field, formed by the two linearly polarized counterpropagating laser beams of relativistic intensities,...
Harmonics generation and intense terahertz radiation from polar molecules at multiphoton resonant excitation in laser fields
laser fields polar molecules Harmonics generation and intense terahertz radiation
2011/9/1
The coherent radiation spectrum of two-level polar molecules with UV transition is studied at the multiphoton resonant excitation by a moderately strong laser field. The spectrum corresponding to harm...
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states
scattering-electron wave packets in strong short-wavelength laser fields Coulomb potential excited states
2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...
Wavelength and intensity dependence of multiple forward scattering at above-threshold ionization in mid-infrared strong laser fields
Wavelength intensity forward scattering above-threshold ionization
2010/11/16
The nonperturbative role of multiple forward scattering for Coulomb focusing in mid-infrared laser fields and its dependence on a laser intensity and wavelength are investigated for low-energy photoe...
Time-resolved analysis of strong-field induced plasmon oscillations in metal clusters by spectral interferometry with few-cycle laser fields
Time-resolved analysis strong-field induced plasmon oscillations metal clusters
2010/11/16
We propose a scheme for ultrafast real-time imaging of laser-induced collective electron oscillations (Mie plasmons) in gas phase metal clusters by interferometrically stable scanning of two intense ...
Direct Ionization Desorption of Fullerene by Intense Femtosecond Laser Fields
C60 Solid Femtosecond Ionization
2009/6/1
We investigated the direct ionization and desorption of solid C60 by the irradiation of femtosecond nonresonant (neutral and cationic states) pulses at 1.4 µm. We concluded that ion desorption i...
