  We confront the generally small cross sections for gluino pair production in
e^+e^- annihilation with the much larger ones in photon-photon scattering at a
multi-TeV linear collider like CERN CLIC. The larger rates and the steeper rise
of the cross section at threshold may allow for a precise gluino mass
determination in high-energy photon-photon collisions for a wide range of
squark masses and post-LEP SUSY benchmark points.
