Light for the Future: Excimer and Free Electron Lasers

摘要

The status of the art of two interesting kind of coherent radiation sources (excimer and free electron lasers) is described. The working principles of excimer lasers is analyzed together with the most relevant characteristics (active media, operating wavelenght, average and peek power, spectrum and time structure). As to the free-electron laser, whose development is at the very first stage, theoretical and experimental aspects are described and perspectives for the future are discussed.
