Abstract
The object of the invention is a free electron laser with two self-stimulating ondulators at higher order harmonics comprising, in combination, a first section comprising an ondulator (UM1) operating as an oscillator, to generate coherent radiation with a determinate wave length (.lambda.) and simultaneously the higher harmonics relevant thereto, and a second section comprising an ondulator (UM2) operating as an amplifier, tuneable at the frequency and the relevant harmonics of the coherent radiation generated in the first modulator (UM1).
Claims11
A free electron laser, comprising:
- oscillator means for generating coherent radiation at a determinate frequency and at higher order harmonic frequencies of said determinate frequency;
- and
- amplifier means for amplifying said coherent radiation at said at least one of said higher order harmonic frequencies generated by said oscillator means, said amplifier being tuneable to at least one of said higher order harmonic frequencies.
A method of producing a free electron laser beam, comprising the steps of:
- generating a coherent radiation at a determinate frequency and at higher order harmonic frequencies of said frequency;
- and
- amplifying said coherent radiation at said at least one of said higher order harmonic frequencies.
