  We examine the process $\gamma \gamma \to \tilde{\chi}^{+} \tau^{-}$ at
photon-photon collider in the minimal supersymmetric standard model(MSSM) with
R-parity violation, where all the one-loop diagrams are considered. We mainly
discuss the effects of bilinear breaking terms, and conclude that their
contributions may be important compared with trilinear terms. Our results show
that the events of this process could be detectable at photon-photon colliders,
if the values of the parameters are favorable.
