- Abstract
- For a tightly focused laser, the beam-waist radius is of the same order as the wavelength and the lower-order-corrected Gaussian pulse description satisfies Maxwell's equations less accurately, so it, becomes necessary to include all the field components that arise from the tight focusing of the laser so as to satisfy Maxwell's equations more accurately. The effect of the seventh-order-corrected chirped Gaussian laser beam on the electron acceleration in vacuum is investigated. A numerical simulation shows that an electron maximum energy gain on the order of giga-electron volts (GeV) can be expected in the beam-waist region 45 <= k(0)w(0) <= 60, where k(0) is the laser wave number and w(0) is the laser-beam's waist size at the focal point of the beam.
