Abstract

The paper examines the generation of an ultrashort pulse in a laser plasma and its amplification using a free-electron laser undulator during interaction with a relativistic electron bunch, including that produced by a petawatt laser. The goal of this study is to determine the system parameters that enable the generation and significant amplification of ultrashort pulses, with durations down to an attosecond.
