Stabilization of ionization due to two color laser fields

  • R. Sharma
  • M. Mohan


We examine the excitation dynamics of a model atom excited by a two commensurate (the fundamental and second harmonic) intense laser fields. We investigate that one can easily stabilize the quantum wave packet through suppression of photodetachment by changing the laser intensity and the relative phase between the two colors.
