The forward ponderomotive force associated with an intense short laser pulse, propagating in a tenuous plasma, accelerates the electrons to velocities higher than the group velocity of the laser. In this work, a simple general solution for ponderomotive acceleration is presented for arbitrary polarization. The circular polarization is more efficient than linear polarization, since the threshold laser intensity needed for electron acceleration is lower for a circularly polarized laser pulse.
