We calculate the squarks one-loop corrections to the cross sections of the chared Higgs boson pair production in photon-photon collisions in the minimal supersymmetric extension of standard model(MSSM). In general, in case of the large splitting in the masses of left-top squark and the right-top squark and for tanβ 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− 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(αmt2/mW2) Yukawa corrections in previous literature.
