Title: Suppression of electron scattering by the longitudinal components of tightly focused laser fields

Abstract

Relativistic electron scattering by a high intensity linearly polarized Gaussian (TEM{sub 00} mode) laser beam is studied in detail using three-dimensional numerical simulations. It is observed that the longitudinal components of the electromagnetic field in a tight focus effectively suppress transverse electron scattering in the relativistic laser ponderomotive acceleration scheme. The simulations show that the relativistic ponderomotive acceleration can produce high quality electron bunches characterized by an extremely short bunch length of subfemtosecond, energy spread less than 1%, and normalized transverse emittance less than 10{pi} mm mrad.
