Query: Anomalous Couplings in Single Higgs Production through $\gamma\gamma$
  Collisions   We show that single Higgs production in $\gamma\gamma$ collisions through
laser backscattering provides the best way to look for New Physics (NP) effects
inducing anomalous Higgs couplings. Our analysis is based on the four $dim=6$
operators $\O_{UB}$, $\O_{UW}$, $\ol{\O}_{UB}$ and $\ol{\O}_{UW}$ which
describe New Physics effects in this sector. Using the Higgs production rate we
establish observability limits for the couplings of the aforementioned
operators at a level of $10^{-3}$, which means establishing lower bounds on the
scale of NP of the order 30 to 200 TeV. Higgs branching ratios, especially the
ratio $\Gamma(H\to\gamma\gamma)/\Gamma (H\to\gamma Z)$, are shown to provide
powerful ways to disentangle the effects of the various operators.
