We investigate the sparticle production processes eγ\goto \sele\sz1 and γγ\goto \sfermion\sfermion at high energy eγ and γγ colliders in the framework of the minimal supersymmetric standard model (MSSM). It will be shown that the eγ colliders would be more suitable in searching for the heavy selectrons than ee colliders because of the low mass threshold of the process eγ\goto \sele\sz1. We show that the standard background processes eγ\goto νW and eZ can be suppressed in terms of initial beam polarization as well as the kinematical cuts on the energy and angle of the final electron. Moreover, it will be argued that the experimental measurements of the cross sections for the processes eγ\goto \sele\sz1 and γγ\goto \sfb\sf could enable us to constrain the basic parameters in the MSSM. This is originated from the simplicity of SUSY parameter dependence of these processes. We also give comments on the stop production at e+e- colliders with the longitudinally polarized electron beams.
