The production of a hard photon balanced by a jet in the reaction γ+γ → jet+γ+X is shown to offer a good probe of the hadronic structure of the photon at e+e- colliders. The cross section for pTγ > 1.5 GeV ranges from ~0.3 pb at PEP to ~1p TRISTAN to ~6 pb at LEP 200. For > √s ≥150GeV, the study of this process will yield important information on the gluon density inside the photon, about which very little is known experimentally at present.
