We study the problem of the Zitterbewegung of electrons in a bilayer graphene system with a perpendicular magnetic field stimulated by a short Gaussian laser pulse. We investigate the response of electrons in the occupied Landau level and find that the dipole moment shows an evident oscillatory behavior while the produced electric field exhibits strong coherent characters in the time evolution which is in favor of experimental observation for ZB. A comparison of the results with the case of graphene monolayer is made. We discuss the implications of these results.
