Perturbative QCD one-loop corrections to the cross sections of the $b\bar b$$(c\bar c)$ quark pair production in polarized photon-photon collisions, aswell as cross sections of the radiative processes photon-photon ->$b\bar bg$,$c\bar c g$ leading to two- and three-jet final states are calculated. It isshown that the signal from the intermediate mass Higgs boson is observable andprecise measurements of the Higgs boson two-photon width are possible at aphoton-photon collider, although the statistical significance is substantiallyreduced with respect to the tree level calculations. We demonstrate thatvirtual corrections are of the same order or larger than the Born contributionin the $J_z=0$ channel at high energy for small values of the cutoff $y_{cut}$,separating two-jet from three-jet topologies. The nature of these largecorrections is elucidated. For $b\bar b$ pair production at$\sqrt{s_{\gamma\gamma}}\sim 100$~GeV and for small values of $y_{cut}\leq0.04$ the higher order resummation of double logarithmic terms ${\calO}\left(\alpha_s m_b^2/s\ln^2(s/m_b^2)\right)$ is needed.Comment: 18 pages, LaTeX, 13 Postscript figures, uses epsfig.st
