Ionization of Xe in intense, two-cycle laser fields: Dependence on carrier-envelope phase
[article]
2017
arXiv
pre-print
We report on tunnel ionization of Xe by 2-cycle, intense, infrared laser pulses and its dependence on carrier-envelope-phase (CEP). At low values of optical field (E), the ionization yield is maximum for cos-like pulses with the dependence becoming stronger for higher charge states. At higher E-values, the CEP dependence either washes out or flips. A simple phenomenological model is developed that predicts and confirms the observed results. CEP effects are seen to persist for 8-cycle pulses.
