摘要：
We present methods to measure the beam polarizations and the luminosity of gamma gamma colliders at TeV energy scale. The beam polarizations of a gamma gamma collider can easily be monitored by comparing the numbers of events of the processes gamma gamma --> l(+)l(-) and gamma gamma --> W+ W-, where l means e or mu. The luminosity of a gamma gamma collider is also measurable by the event rate of W boson pair productions and the light lepton pair productions.
