Description
Compton back-scattering has been demonstrated to provide compact, highly
tunable, versatile and not expensive sources of X-gamma rays. New
possibilities of improving the performances of the Compton sources are
discussed. One of the methods for increasing the spectral density is
based on the chirp of the laser. In this way, the oscillations and the
broadening of the spectrum occurring in non linear regime can be
eliminated, obtaining highly monochromatic signals. The occurrence of
collective effects, taking place when the laser has high energy and long
pulses permits to increase both the spectral density and the total number
of photons. The control of polarization, the encoding of orbital momentum
on the radiation and the possibility of producing two color radiation are
also presented. Furthermore, the collisions between the gamma photons
produced by two Compton scatterings provide an efficient way to test the
QED photon-photon physics.
