Attosecond pulse formation via switching of resonant interaction by tunnel ionization Conference Paper uri icon

abstract

  • © 2015 SPIE. We investigate a new method to produce attosecond pulses from a resonant XUV radiation in an atomic gas which is simultaneously irradiated by an IR laser field. Around the crests of an IR field all the excited atomic energy levels are strongly broadened due to rapid tunnel ionization from the corresponding excited states and atoms are not able to resonantly absorb the incident vacuum ultraviolet radiation. Vice versa, around zeroes of an IR field, ionization is slow and atoms effectively absorb the vacuum ultraviolet radiation. As a result, an interaction between atoms and XUV field is switched on and off resulting in formation of attosecond pulses.
