Title: Wavelength dependence of double ionization of xenon in a strong laser field

Abstract

The wavelength dependence of double ionization of xenon in a 100-fs laser pulse (2-4x10{sup 13} W/cm{sup 2}) has been studied using photoelectron imaging and ion time-of-flight spectrometry. In the wavelength ranges between 1150 and 1560 nm and 792 and 803 nm a pronounced variation of the ratio of ion yields Xe{sup 2+}/Xe{sup +} is observed. We attribute this variation to the strong influence of a 5s{sup 2}5p{sup 5}{yields}5s5p{sup 6} transition on the dynamics of double ionization.

  • The wavelength and intensity dependence of xenon ionization with 50 fs laser pulses has been studied using time-of-flight mass spectrometry. We compare the ion yield distribution of singly and doubly charged xenon with the Perelomov-Popov-Terent'ev (PPT) theory, Perelomov, Popov, and Terent'ev, Zh. Eksp. Teor. Fiz. 50, 1393 (1966) [Sov. Phys. JETP 23, 924 (1966)], in the regime between 500 and 2300 nm. The intensity dependence for each wavelength is measured in a range between 1x10{sup 13} and 1x10{sup 15} W/cm{sup 2}. The Xe{sup +}-ion signal is in good agreement with the PPT theory at all used wavelengths. In addition wemore » demonstrate that ionic 5s5p{sup 6} {sup 2}S state is excited by an electron impact excitation process and contributes to the nonsequential double ionization process.« less
  • We extend the coupled coherent-state (CCS) approach to simulate the strong-field ionization of helium atoms at long wavelengths. This approach uses a basis of trajectories guided by frozen Gaussian coherent states, sampled from a Monte Carlo distribution, as the initial states of the quantum time-dependent Schroedinger equations. The CCS trajectories move over averaged potentials, which can remove the Columbic singularities exactly. The low-energy structure is predicted by our CCS calculation and a ''rescattering'' event is clearly identified in the higher-energy regime. In addition, the nonsequential double ionization is also explored and the rescattering event can be identified as the majormore » mechanism. Finally, we also study the electron angular distribution of helium. It is found that the maximum angle between the electron and electric field directions becomes smaller with increase in the laser intensity and wavelength.« less
  • The emission energy of continuously operated double-heterostructure GaAs-AlGaAs lasers has been measured in magnetic fields up to 15 T and temperatures of 4.2 and 50 K. For lasers with a p-active region the observed shift in the emission energy can be described by a change in the position of the quasi-Fermi level of the conduction band as a function of the magnetic field. The measurements provide a determination of the carrier density at threshold and verify the assumption that the matrix element for the optical transition is in first order independent of the applied magnetic field.
  • We provide the first uniform explanation basis for the laser intensity dependence of the momentum distributions that have been reported in atomic nonsequential double-ionization experiments. Our theoretical work covers laser irradiation at 780 nm and intensities in the range I=(1-6.5)x10{sup 14} W/cm{sup 2}, which are relevant to experiments. We use a completely classical method introduced previously [Phay J. Ho, R. Panfili, S. L. Haan, and J. H. Eberly, Phys. Rev. Lett. 94, 093002 (2005)]. Our calculated results suggest that just two distinct categories of electron trajectories are relevant.
