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

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;
- and
- 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,
- said method being characterized in that it comprises:
- 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.
An electromagnetic radiation source comprising:
- a laser source to fire a first laser pulse;
- means for generating a plasma region, the first laser pulse penetrating at least partially into said plasma region to create a plasma density wake in said plasma region;
- and
- means for providing a group of charged particles in the plasma region, said group of charged particles being arranged so as to be accelerated in the plasma density wake of the first laser pulse, said source being characterized in that it comprises
- means for 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, said reflected laser pulse being arranged to interact with the group of charged particles and generate an electromagnetic radiation.
