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…

Laser-based metastable krypton generation
M. A. Dakka, G. Tsiminis, P. S. Light +6
We demonstrate the generation of metastable krypton in the long-lived 1s5 state using laser excitation. The atoms are excited through a two-photon absorption process into the 2p6 s…
