Dipole Phase Evolution of Laser-Dressed Autoionizing States in Neon

Dipole Phase Evolution of Laser-Dressed Autoionizing States in Neon We present theoretical attosecond transient absorption spectroscopy calculations of neon, focusing on the [He] 2s 2p6 3p 1Po autoionizing state, in an extreme ultraviolet pump, near infrared probe configuration. We find that as the two laser pulses overlap, there is a strong shift in the dipole phase, which we attribute to an effective reduction in the coupling strength between the bound and continuum states as the near infrared pulse makes new pathways accessible. To quantitatively analyze the dipole phase in the presence of perturbed free induction decay we demonstrate a novel method to obtain resonance phase and strength values directly from the dipole spectrum.
