The gamma-gamma luminosity in collisions of virtual photons at e+e- storage rings is much lower than that in e+e- collisions and the spectrum is rather soft. In 1980 we have noticed that at high energy linear colliders beams are used only ones which makes possible to convert electrons to high energy photons using Compton scattering of laser photons and thus to obtain real gamma-gamma collisions with energies and luminosities similar to e+e- collisions. Such high energy gamma-gamma (gamma-electron) colliders are technically feasible now and are considered as a natural option in all e+e- linear collider projects
