The reaction e(+)e(-) --> e(+)e(-)gamma (*)gamma (*) --> e(+)e(-) hadrons for quasi-real photons is studied using data from roots = 183 GeV up to 202 GeV. Results on the total cross sections sigma (e(+)e(-) -->e(+)e(-) hadrons) and sigma (gamma gamma --> hadrons) are given for the two-photon centre-of-mass energies 5 GeV less than or equal to W gamma gamma less than or equal to 185 GeV, The total cross section of two real photons is described by a Regge parametrisation. We observe a steeper rise with the two-photon centre-of-mass energy as compared to the hadron-hadron and the photon-proton cross sections. The data are also compared to the expectations of different theoretical models. (C) 2001 Published by Elsevier Science B.V.
