Abstract: The effect of the pulse-shape, carrier-envelope phase (CEP) and number of cycles of the ultra-intense, ultra-short few-cycles TM01 laser propagating in vacuum on the acceleration of the electrons has been analytically and numerically investigated. The Gaussian, Lorentzian, and hyperbolic-secant temporal profiles of the laser pulse have been considered to get an insight into the scheme of acceleration of charged particles. A laser of intensity ~1022 W/cm2 is found to accelerate the on-axis electrons from rest to the GeV energy range. The numerical results show that a single cycle Lorentzian profile of the laser pulse may mainly be used to obtain the higher values of possible electron acceleration.
