Interference of electrons ionized by short laser pulses
We analyze the two-dimensional momentum distribution of electrons ionized by short laser pulses by solving the time-dependent Schrödinger equation. Lindner et al., [Phys. Rev. Lett. 95, 040401 (2005)] identified oscillations in the electron emission spectrum for ionization by a few-cycle pulse as a...

| Sumario: | We analyze the two-dimensional momentum distribution of electrons ionized by short laser pulses by solving the time-dependent Schrödinger equation. Lindner et al., [Phys. Rev. Lett. 95, 040401 (2005)] identified oscillations in the electron emission spectrum for ionization by a few-cycle pulse as a time-double slit interference. We extend this analysis to interference fringes in the momentum distributions. For longer pulses we find a complex two-dimensional interference pattern that resembles ATI rings at higher energies and displays Ramsauer - Townsend - type diffraction oscillations in the angular distribution near threshold. © 2007 IOP Publishing Ltd. |
