  We calculate total and differential cross sections for the production of
sfermion pairs in photon-photon collisions, including contributions from
resolved photons and arbitrary photon polarization. Sfermion production in
photon collisions depends only on the sfermion mass and charge. It is thus
independent of the details of the SUSY breaking mechanism, but highly sensitive
to the sfermion charge. We compare the total cross sections for bremsstrahlung,
beamstrahlung, and laser backscattering photons to those in $e^+e^-$
annihilation. We find that the total cross section at a polarized photon
collider is larger than the $e^+e^-$ annihilation cross section up to the
kinematic limit of the photon collider.
