Abstract
The luminosity distribution in the effective
mass
at a photon collider usually has two peaks which are well
separated: a high energy peak with mean energy spread about
5-7% and a wide low energy peak. The low energy peak strongly
depends on the details of the design and is unsuitable for the
study
of
new physics phenomena. We find a simple approximate form for
the spectra
of colliding photons for
