Reconstruction of Atomic Ionization Probabilities in Intense Laser Fields
Application of a parallel-projection inversion technique to z-scan spectra of multiply charged xenon and krypton ions, obtained by non-resonant field ionization of neutral targets, has for the first time permitted the direct observation of intensity-dependent ionization probabilities. These ionization efficiency curves have highlighted the presence of structure in the tunnelling regime, previou...
متن کاملTheory of Gas Ionization by Intense Electromagnetic Fields
The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...
متن کاملMultiple Ionization of Atoms in Intense Laser Fields
A new ultrahigh vacuum-compatible ( 10 11 mbar) "reaction microscope" was built to investigate multiple ionization of atoms and molecules in ultra-short (23 fs), intense laser pulses (1014 1016 W/cm2, 795 nm) . In first experiments ion momentum distributions for single and double ionization of noble gas atoms in the nonsequential and sequential intensity regime were measured using linearly pola...
متن کاملSaturated ionization of fullerenes in intense laser fields.
We investigate the ionization of icosahedral fullerenes (C20, C60, C80, and C180) in an intense laser pulse using the S-matrix theory. The results obtained are in excellent agreement with the recent observations of unexpectedly high saturation intensities of the Buckminster fullerene and its multiply charged ions. Our analysis strongly suggests that the related phenomenon of suppressed ionizati...
متن کاملGeometry- and diffraction-independent ionization probabilities in intense laser fields: probing atomic ionization mechanisms with effective intensity matching
We report a novel experimental technique for the comparison of ionization processes in ultrafast laser pulses irrespective of pulse ellipticity. Multiple ionization of xenon by 50 fs 790 nm, linearly and circularly polarized laser pulses is observed over the intensity range 10 TW/cm to 10 PW/cm using Effective Intensity Matching (EIM), which is coupled with Intensity Selective Scanning (ISS) to...
