We study heavy physics effects on the Higgs production in $gamma gamma $ fusion using the effective Lagrangian approach. We find that the effects coming from new physics may enhance the standard model predictions for the number of events expected in the final states $bar bb$, $WW$, and $ZZ$ up to one order of magnitude, whereas the corresponding number of events for the final state $bar tt$ may be enhanced up to two orders of magnitude.
