We examine the process gamma gamma -> W+W- in context of a gamma gamma collider constructed by backscattering laser light off the electron bems of a 500-GeV e+e- collider. We present analytic formulas for the helicity amplitudes with general kappa and lambda anomalous couplings. We calculate the effective cross section, accounting for the photon spectrum and including polarization effects. Finally, we assess the sensitivity of this experiment, and compare with those of other experiments running at a comparable energy.
