Extracting RABBITT-like phase information from time-dependent transient absorption spectra
J. Jakob, C. Bauer, M. -J. Ilhan +5
We explore how the spectral phase of atto\-second pulse trains influences the optical cross section in transient absorption (TA) spectroscopy. The interaction of extreme ultraviole…
Circular Dichroism in Multiphoton Ionization of Resonantly Excited Helium Ions near Channel Closing
Rene Wagner, Markus Ilchen, Nicolas Douguet +16
The circular dichroism (CD) of photoelectrons generated by near-infrared (NIR) laser pulses using multiphoton ionization of excited He ions in the 3p(m=+1) state. The ions were…
Photoelectron momentum distributions in the strong-field ionization of atomic hydrogen by few-cycle elliptically polarized optical pulses
Nicolas Douguet, Klaus Bartschat
We investigate the strong-field ionization of atomic hydrogen in a few-cycle elliptically polarized infrared pulse by solving the time-dependent Schrödinger equation. The dependenc…
Two-path interference in the resonance-enhanced few-photon ionization of atoms
B. P. Acharya, S. Dubey, K. L. Romans +6
We investigate the resonance-enhanced few-photon ionization of atomic lithium by linearly polarized light whose frequency is tuned near the 2s-2p transition. Considering the direct…
Magnetic Dichroism in Few-Photon Ionization of Polarized Atoms
B. P. Acharya, M. Dodson, S. Dubey +7
We consider few-photon ionization of atomic lithium by linearly polarized femtosecond laser pulses, and demonstrate that asymmetries of the electron angular distribution can occur…
Carrier-Envelope-Phase Dependent Strong-Field Excitation
D. Chetty, R. D. Glover, X. M. Tong +9
We present a joint experimental-theoretical study on the effect of the carrier-envelope phase (CEP) of a few-cycle pulse on the atomic excitation process. We focus on the excitatio…
