  In this paper, we present predictions for scattering cross-section the of
Higgs boson pair production via photon fusion at future muon colliders,
focusing specifically the production processes $\mu^+\mu^- \rightarrow
\gamma\gamma \rightarrow h^0h^0, A^0A^0$. We investigated the impact of three
choices the photon structure functions on cross-section predictions for a range
model input parameters within the theoretical framework of the Higgs Triplet
Model.
