Abstract The {ital O}({alpha}{ital m}{sup 2}{sub {ital t}}/{ital m}{sup 2}{sub {ital W}}) Yukawa corrections to bottom quark pair production via photon-photon fusion in TeV {ital e}{sup +}{ital e}{sup {minus}} colliders are calculated in both the general two-Higgs-doublet model and minimal supersymmetric model. We find that the corrections to the cross section of the subprocess {gamma}{gamma}{r_arrow}{ital b{bar b}} can be a few percent. The corrections to the total cross section of the process {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{gamma}{gamma}{r_arrow}{ital b{bar b}} in the beamstrahlung photon fusion mode are rather small and can be ignored at the one-loop level; however, the corrections in the Compton backscattering photon fusion mode may approach 0.1{percent} for favorable parameter values. {copyright} {ital 1996 The American Physical Society.}
