Subcycle interference dynamics of time-resolved photoelectron holography with midinfrared laser pulses

摘要

Time-resolved photoelectron holography from atoms using midinfrared laser pulses is investigated by solvingthe corresponding time-dependent Schrodinger equation (TDSE) and a classical model, respectively. Thenumerical simulation of the photoelectron angular distribution of Xe irradiated with a low-frequency free-electronlaser source agrees well with the experimental results. Different types of subcycle interferometric structures arepredicted by the classical model. Furthermore with the TDSE model it is demonstrated that the holographicpattern is sensitive to the shape of the atomic orbitals. This is a step toward imaging by means of photoelectronholography.
