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…
Strong field ionisation of Argon: Electron momentum spectra and nondipole effects
Nida Haram, Han Xu, Igor Ivanov +3
We investigate the influence of relativistic nondipole effects on the photoelectron spectra of argon, particularly in the low kinetic energy region (0 eV - 5 eV). In our experiment…
Ellipticity Dependence of Excitation and Ionization of Argon Atoms by Short-Pulse Infrared Radiation
Thomas Pauly, Aaron Bondy, Kathryn R. Hamilton +4
When atoms or molecules are exposed to strong short-pulse infrared radiation, ionization as well as "frustrated tunneling ionization" (FTI) can occur, in which a portion of the alm…
Observation of Dynamic Stark Resonances in Strong-Field Excitation
Dashavir Chetty, Rohan D. Glover, Bruno A. deHarak +12
We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses. Using 30 fs pulses we observe periodic enhancements of the excitation yield in the intensi…
Relativistic non-dipole effects in strong-field atomic ionization at moderate intensities
Nida Haram, Igor Ivanov, Han Xu +7
We present a detailed experimental and theoretical study on the relativistic non-dipole effects in strong-field atomic ionisation by near-infrared linearly-polarised few-cycle lase…
