  The cross sections for the lightest neutral Higgs pair production at the
one-loop level in photon-photon collisions are calculated in the Minimal
Supersymmetric Standard Model(MSSM). We find that the contributions to the
lightest Higgs boson pair production cross sections arising from the genuine
supersymmetric virtual particles dominate over that arising from the virtual
particles in the two-Higgs-doublet model (2HDM) if there are mixing between the
right- and left-handed stops, otherwise, the contributions from ones in the
2HDM are dominant. We present the detailed numerical results of the cross
sections of the process $e^+e^-\to \gamma\gamma \to h_0h_0$ in both
beamstrahlung and laser back scattering photon modes at the Next Linear
Collider (NLC). The cross sections are typically in the range of $10^{-3}fb $
to $10^5 fb$ depending on the choice of the mass of the lightest neutral Higgs
boson, $\tan\beta$ and photon collision modes, especially whether there are
mixing between the stops.
