We calculate total and differential cross-sections for sfermion production
in e(+)e(-) annihilation and in photon photon collisions with arbitrary pho
ton polarization. The total cross-section at a polarized photon collider is
shown to be larger than the e(+)e(-) annihilation cross-section up to the
kinematic limit of the photon collider. (C) 2001 Elsevier Science B.V. All
