Abstract
A review of the recent experimental results on two-photon physics at LEP2 is presented. Differential cross-sections are measured for double-tagged hadronic γγ events by the ALEPH and OPAL collaborations. Single particle inclusive differential cross-sections are measured by the L3 experiment at center-of-mass energies between 189 GeV and 202 GeV. For the first time at LEP the production of prompt photons is studied in the collision of quasi-real photons using data taken by the OPAL experiment at LEP2 energies.
