Complete analytical results for the production of heavy-quark pairs by polarized and unpolarized photons in next-to-leading order are presented. Two-, three- and two plus three-jet cross sections for total photon spin Jz=0,± 2 are presented for bb(g) production. The 2-jet cross sections are considered as a background to γγ→ H* → bb (standard model). Top production, not too far above threshold, is also considered for Jz=0,± 2. For both b- and t-quark production, the higher order QCD corrections are found to be significant.
