  Results from a realistic simulation of the heavy MSSM Higgs-bosons A and H
production, gamma gamma -> A,H -> b bbar, at the Photon Collider at TESLA are
reported. In the scenario where a light SM-like Higgs boson h exists, we study
(following M. Muehlleitner et al.) Higgs bosons A and H for masses
M_A=200,250,300,350 GeV and tan(beta)=7. This scenario corresponds to
parameters region not accessible at LHC or at the first stage of the e^+ e^-
collider. NLO estimation of background, analysis of overlaying events,
realistic b-tagging and corrections for escaping neutrinos were performed. The
statistical precision of the cross-section measurement is estimated to be
8-20%.
