Electroweak radiative one-loop corrections to the process {gamma}{gamma}{r_arrow}W{sup +}W{sup {minus}} with photon and W-boson polarizations are calculated within the two-Higgs-doublet model extension of the standard model, and the relevant analytical results for the nonstandard Higgs bosons contributions to the helicity amplitudes are given. The relative difference between the predictions of the two-Higgs-doublet model and minimal standard model for a light salar M{sub H{sub 1}} and heavy M{sub H{sub 2}} and M{sub {Phi}} easily exceed {plus_minus}20{percent} for W{sub T}W{sub T} pair production in the central angular region at high energy, and even larger for W{sub L}W{sub L} pair production. The angular dependence corrections owing to the nonstandard Higgs boson get larger, where box diagrams constitute the dominant part of the radiative corrections. {copyright} {ital 1997} {ital The American Physical Society}
