The next generation electron-positron colliders are designed for precisionstudies of the Standard Model and its extensions, in particular in the Higgssector. We consider the potential for discovery of composite Higgs models inHiggs pair production through photon collisions. This process isloop-generated, thus it provides access to all Higgs couplings and can show newphysics effects in polarized and unpolarized cross-sections starting atrelatively low collider energies. It is, therefore, relevant for allelectron-positron colliders planned or in preparation. Sizeable deviations fromthe Standard Model predictions are present in a general class of compositeHiggs models, as couplings of one or more Higgs bosons to fermions, orfermionic and scalar resonances, modify the destructive interference present inthe Standard Model. In particular, large effects are due to the new quarticcoupling of the Higgs to tops and to the presence of a light scalar resonance.
