Photon collider at the ILC

This talk was given at the workshop on high energy gamma-gamma collisions at the LHC, where this type of collision presents for free but physics here, certainly, can not compete with that in basic quark and gluon collisions. At the photon collider, discussed below, the γγ luminosity will be higher than at the LHC by a factor of 1000 at the h(130) mass! In this talk an overview basic principles, possible parameters, technical aspects and physics program (shortly) is given and present status of the photon collider at the ILC is discussed.
