Усиление коротковолновых субаттоимпульсов в лазере нa свободных электронах при помощи электронов, ускоренных в лазерной плазме

Abstract

The amplification in a free-electron laser undulator of a short-wavelength subattosecond pulse formed in a laser plasma upon its interaction with a relativistic electron bunch produced by a petawatt laser is considered. The aim of this work is to find the parameters of the system at which it is possible to amplify ultrashort pulses with a duration of up to hundreds of zeptoseconds.
