Atomic excitation during recollision-free ultrafast multi-electron tunnel ionization
W. A. Bryan, S. L. Stebbings, J. McKenna +12
Modern intense ultrafast pulsed lasers generate an electric field of sufficient strength to permit tunnel ionization of the valence electrons in atoms. This process is usually trea…
Attosecond signatures in photodissociation by an intense Ti:Sapphire pulse
J F McCann, Liang-You Peng, I D Williams
In our model the electron dynamics are described by a two-state approximation. This might appear a rough approximation since it neglects coupling through excited electronic states…
Extreme UV generation from molecules in intense Ti:Sapphire light
J F McCann, Liang-You Peng, I D Williams +2
We simulate the dynamics of H2+ and HD+ by direct solution of the time-dependent Schroedinger equation for the electronic and nuclear motion for the interaction of intense femtosec…
On the recollision-free excitation of krypton during ultrafast multi-electron tunnel ionization
W A Bryan, S L Stebbings, J McKenna +7
The probability of multiple ionization of krypton by 50 femtosecond circularly polarized laser pulses, independent of the optical focal geometry, has been obtained for the first ti…
Reconstruction of Atomic Ionization Probabilities in Intense Laser Fields
T. R. J. Goodworth, W. A. Bryan, I. D. Williams +1
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,…
Geometry- and diffraction-independent ionization probabilities in intense laser fields: probing atomic ionization mechanisms with effective intensity matching
W. A. Bryan, S. L. Stebbings, E. M. L. English +11
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…
