ALL OPTICAL HIGH ENERGY RADIATION SOURCE

摘要

A method for producing electromagnetic radiation comprising : firing a first laser pulse and generating a plasma region, said first laser pulse penetrating at least partially into said plasma region to create a plasma density wake in said plasma region; providing a group of charged particles in the plasma region arranged so as to be accelerated in the plasma density wake of the first laser pulse; reflecting the first laser pulse after said first laser pulse has at least partially penetrated into said plasma region, to give a reflected laser pulse; and arranging said reflected laser pulse to interact with said group of charged particles so as to generate an electromagnetic radiation.
