The picture below is the two dimensional projection of the electron cloud emitted from Xe atoms when they are exposed to a 780 nm, 150 fs laser pulse. It is recorded with our velocity imaging electron spectrometer. The concentric rings represent absorption of 8 photons for the innermost ring, 9 for the next etc.
