Semiclassical interference in photoelectron spectra: Holographic structures

We theoretically investigate on the holographic structure in doubly differential momentum distribution for atomic photoionization. We use the ab initio solution of the time dependent Schrodinger equantion and the two-step semiclassical model. We see how the holographic structures are formed due to the interference of the direct trajectories of electrons and the rescattered trajectories of electrons. We get rid of intra- and intercycle interferences by removing ionization in the second half of a one-cycle pulse.
