Investigation of the photoionization process of helium ion in bichromatic circularly XUV fields with different time delays
Chemical Physics Letters(2019)
摘要
•Photoionization of the atom in bichromatic circularly polarized laser pulses.•The interference of two ionization pathways causes the asymmetrical photoelectron momentum distribution.•Photoelectron momentum distribution is sensitive to the vary of time delay in bichromatic circularly polarized laser pulses.
