Ultrafast photoionization of ions and molecules by orthogonally polarized intense laser pulses: Effects of the time delay

doi:10.1088/1674-1056/abb30c

Abstract We present the photoelectron momentum distributions (PMDs) and the photoelectron angular distributions (PADs) of He⁺ ions, aligned H₂⁺ molecules and N₂ molecules by intense orthogonally polarized laser pulses. Simulations are performed by numerically solving the corresponding two-dimensional time-dependent Schrödinger equations (TDSEs) within the single-electron approximation frame. Photoelectron momentum distributions and photoelectron angular distributions present different patterns with the time delays T_d, illustrating the dependences of the PMDs and PADs on the time delays by orthogonally polarized laser pulses. The evolution of the electron wavepackets can be employed to describe the intensity of the PADs from the TDSE simulations for N₂ molecules.

Keywords: photoelectron momentum distributions photoelectron angular distributions intense orthogonally polarized laser pulses ultrafast photoionization model
