摘要：
Electron acceleration by a frequency - chirped lowest axicon Gaussian laser pulse in vacuum is studied. Terawatt RP laser can be focussed down by an axicon optical element, which produces a very strong longitudinal electric field. A linear frequency chirp increases the time duration of interaction of laser pulse with electron and hence, influences electron motion significantly. It is noticed that an electron with initial energy of few MeV, accelerates upto GeV energy under optimized laser parameters. Significant higher energy gain is observed with intense chirped laser pulse in vacuum.
