  The cross section for massive fermion production in two-photon collisions was
examined at next-to-leading order in QCD/QED for general photon helicity. The
delta function (virtual+soft) part of the differential cross section was
analytically integrated over the final state phase space. Series expansions for
the complete differential and total cross sections were given up to tenth order
in the parameter beta. These were shown to be of practical use and revealed
much structure. Accurate parametrizations of the total cross sections were
given, valid up to higher energies. The above results were applied to top quark
production in the region not too far above threshold. The cross section was
shown to be quite sensitive to alpha_s in the appropriate energy region.
