Resonant formation of few-cycle pulses by hydrogen-like atoms with time-dependent resonance Academic Article

abstract

• We show the possibility of producing a short bunch of nearly bandwidth-limited few-cycle attosecond pulses based on time-dependent resonant interaction of an incident radiation pulse with the bound states of hydrogen-like atoms. Time-dependence of an atomic resonance is provided by a laser pulse far from resonance with an intensity well below the atomic ionization threshold via time-dependent tunnel ionization from the excited states and time-dependent adiabatic Stark splitting of the excited energy levels. Without external matching of the spectral components it is possible to produce pulses with durations up to 80 as at the carrier wavelength of 13.5 nm in Li2+-plasma, as well as pulses with durations up to 600 as at the carrier wavelength of 122 nm in atomic hydrogen. 2013 Astro Ltd.
