  The heavy neutral Higgs bosons H, A in the minimal supersymmetric extension
of the Standard Model can be produced as single resonances at high-energy gamma
gamma colliders. We have studied the prospects of the search for these
particles in b\bar b and neutralino-pair final states. The Higgs bosons can be
found with masses up to 70-80% of the initial e^\pm e^- collider energy for
medium values of tan(beta), i.e. in areas of the supersymmetric parameter space
not accessible at other colliders.
