Controlling non-adiabatic ionization with shaped ultra-short laser pulses

POSTER

Abstract

Ultra-short, high-frequency pulses can drive non-adiabatic photoionization [1]. Fundamentally different from the conventional single-photon channel, the process is sensitive to the derivative of the pulse envelope. This renders non- adiabatic photoionization difficult to control at first glance. Here we device a route how to tailor this process by means of shaped pulses and/or quasi- resonant conditions in the atom, or more generally, the electronic system of the target.
