Few-cycle pulse-driven excitation response of resonant medium with nonlinear field coupling

Abstract

We demonstrate that the resonant medium with essentially nonlinear field coupling can exhibit specific response when excited by the few-cycle optical pulse. We provide an effective theoretical background that allows relating the type of the field coupling function with the medium oscillators output on the few-cycle pulse-driven excitation. Possible applications of such the optical response are discussed for the controllable generation and shaping of the unipolar video pulses.
