Real-time evolution of a laser-dressed Helium atom: Attosecond-resolved two-color photoionization study

Niranjan Shivaram, Henry Timmers, Xiao-Min Tong +1

Using extreme-ultraviolet attosecond-pulse-trains, we investigate the photoionization dynamics of a Helium atom in the presence of moderately-strong (~10^12 W/cm^2) femtosecond las…
