The O(alpha) electroweak radiative corrections to gamma gamma --> WW --> 4f within the electroweak Standard Model are calculated in double-pole approximation (DPA). Virtual corrections are treated in DPA, and real-photonic corrections are based on complete lowest-order matrix elements for gamma gamma --> 4f+gamma. The radiative corrections are implemented in a Monte Carlo generator called COFFERgammagamma, which optionally includes anomalous triple and quartic gauge-boson couplings in addition and performs a convolution over realistic spectra of the photon beams. A brief survey of numerical results comprises O(alpha) corrections to integrated cross sections as well as to angular and invariant-mass distributions.
