Coincidence measurement of two-photon double ionization of argon through an autoionizing resonance
Sebastian Hell, Julian Späthe, Morten Førre +8
We present coincidence measurements of two-photon double-ionization (TPDI) of argon driven by femtosecond pulses tunable around 26.5 eV photon energy, which are obtained from a hig…
Alternative gauge for the description of the light-matter interaction in a relativistic framework
Tor Kjellsson, Morten Førre, Aleksander Skjerlie Simonsen +2
We present a generalized velocity gauge form of the relativistic laser-matter interaction. In comparison with the (equivalent) regular minimal coupling description, this new form o…
One-photon double ionization of helium: a heuristic formula for the cross section
Morten Førre
Without a formal derivation, we propose a formula for the total and single-differential cross in the problem of one-photon double ionization of an atom. The formula is benchmarked…
A numerical study of two-photon ionization of helium using the Pyprop framework
R. Nepstad, T. Birkeland, M. Førre
Few-photon induced breakup of helium is studied using a newly developed ab initio numerical framework for solving the six-dimensional time-dependent Schroedinger equation. We prese…
Exact Nondipole Kramers-Henneberger Form of the Light-Atom Hamiltonian: An Application to Atomic Stabilization and Photoelectron Energy Spectra
M. Forre, S. Selsto, J. P. Hansen +1
The exact nondipole minimal-coupling Hamiltonian for an atom interacting with an explicitly time- and space-dependent laser field is transformed into the rest frame of a classical…
Strong Orientation Effects in Ionization of H by Short, Intense, High-Frequency Light Sources
S. Selsto, M. Forre, J. P. Hansen +1
We present three dimensional time-dependent calculations of ionization of arbitrarily spatially oriented H by attosecond, intense, high-frequency laser fields. The ionization…
