摘要: A novel approach for the generation of ultrabright attosecond electron bunches is proposed, based on acceleration in vacuum, by a short laser pulse. The laser-pulse profile tailored such that electrons are both focused and accelerated ponderomotive force light. Using time-averaged equations motion, analytical criteria optimal regime found. It shown realistic parameters, beam with up to 10{sup 6} particles normalized transverse longitudinal emittances {lt}10{sup {minus}8} m can be produced.
