  In Standard Model (SM) Higgs Boson pair production initiated by photons
($\gamma \gamma \to h h$) is loop-generated process and thereby very sensitive
to any new couplings and particles that may come in loops. The Composite Higgs
Models provide an alternate mechanism to address the hierarchy problem of SM
where Higgs instead of being an elementary field could be a bound state of a
strongly interacting sector. These set of models apart from modifying the SM
Higgs couplings could also introduce new effective couplings that can have
substantial impact on the loop processes. In this work we have studied the
impact of such modifications by Composite Higgs models in $\gamma\gamma \to h
h$ production process.
