Optical Control of Autoionizing States in Argon
摘要
We use tunable attosecond transient absorption to study the autoionizing polaritonic states in argon. Our approach provides new avenues for optical control of autoionization dynamics in polyelectronic systems. We highlight the stabilization of autoionizing states as a function of the detuning and time-delay of the dressing laser pulse. Furthermore, we use the relative polarization between the pump and probe pulses to control the branching of the polaritons, where the selection rules allow us to include or exclude specific states from the radiative coupling.
