  We analyze the effects of a strongly interacting symmetry breaking sector of
the Standard Model in $\gamma \gamma -> W_L^+ W_L^-$ and $\gamma \gamma -> Z_L
Z_L$ reactions at TeV energies by using Chiral Lagrangians and Chiral
Perturbation Theory. We find significant deviations from the Standard Model
predictions for the differential cross sections at high invariant mass of the
gauge bosons pair. We study the experimental signals that could be obtained in
a high energy and high luminosity dedicated $\gamma\gamma$ collider and
estimate the sensitivity that such experiments could reach to the values of the
effective lagrangian parameters.
