  The complete analysis of the CP violation in the process $\gamma \gamma \to t
\bar{t}$ in frame of the Minimal Supersymmetric Model(MSSM) is presented. The
CP-odd observables for describing the CP violating effects in polarized and
unpolarized photon collisions, are calculated. We investigate the possible CP
violation sources induced by the complex soft breaking parameters and study the
CP violating effects contributed by gluino, neutralino and chargino sectors
appearing in the loop diagrams. We find that it is possible to observe the CP
violation effects in top quark pair production via polarized and unpolarized
photon fusions by using optimal observables and favorable parameters.
