An e+e- linear collider offers the possibility to be used also as a gamma-gamma or gamma-electron collider. A high-intensity photon beam be is created by Compton scattering of the high-energy electrons with a high-intensity laser beam a few millimeter distance of the IP. Luminosity and energy of a gamma-gamma collider is comparable to the e+e- case. Further information can be found in the Appendix 1 of the TESLA TDR
The LC group in Zeuthen also worked on the preparation of this option. Main research subjects were
