We calculate the squark one-loop corrections to the cross sections of charged Higgs boson pair production in photon-photon collisions in the minimal supersymmetric extension of the standard model. In general, in the case of a large splitting in the masses of the left-top squark and the right-top squark and for tan\ensuremathβ near 1.5, the corrections can reduce the cross sections by more than 10% for a wide range of the charged Higgs boson mass, depending on the e+e^\ensuremath- center-of-mass energy. But in other cases, the corrections are at most only a few percent. Those corrections can be comparable to the O(\ensuremathαmt2/mW2) Yukawa corrections in the previous literature.
