1. Ponderomotive dressing of doubly-excited states with intensity-controlled laser light

Author

Subjects
Physics, QC1-999
Abstract

We laser-dress several doubly-excited states in helium. Tuning the coupling-laser intensity from perturbative to the strong-coupling regime, we are able to measure phases imprinted on the two-electron wavefunctions, and observe a new continuum coupling mechanism.

2. Time-resolved spectroscopy of doubly-excited states in helium

Author

Ding Thomas, Hagstotz Steffen, Zhang Yizhu, Laux Martin, Meyer Kristina, Raith Philipp, Kaldun Andreas, Ott Christian, Heck Robert, and Pfeifer Thomas

Subjects
Physics, QC1-999
Abstract

A two-electron wave packet among the lowest-lying doubly-excited states in helium is experimentally observed. It creates a 1-femtosecond modulation in the transient-absorption signal modified by a time-delayed coupling laser.
