We describe a possibility of creating non-stationary electron wave packets inzigzag carbon nanotubes (CNT) illuminated by short laser pulses. Afterdisappearance of the pulse the packet experiences the trembling motion(Zitterbewegung, ZB). The band structure of CNT is calculated using thetight-binding approximation generalized for the presence of radiation.Employing realistic pulse and CNT parameters we obtain the ZB oscillations withinter-band frequencies corresponding to specific pairs of energy bands. Achoice of optimal parameters is presented in order to observe the phenomenon ofZB experimentally. The use of Gaussian wave packets to trigger the electronZitterbewegung, as used in the literature, is critically reexamined.
