The {ital O}({alpha}{ital m}{sup 2}{sub {ital t}}/{ital m}{sup 2}{sub {ital W}}) Yukawa corrections to top quark pair production in photon-photon collisions are calculated in the standard model (SM), the general two-Higgs-doublet model (2HDM), as well as the minimal supersymmetric model (MSSM). We found that the correction to the cross section can only reach a few percent in the SM, but can be quite significant ({gt}10{percent}) in the 2HDM and MSSM for favorable parameter values, which may be observable at high energy {ital e}{sup +}{ital e}{sup {minus}} colliders. {copyright} {ital 1996 The American Physical Society.}
