The photon polarization operator (PO) in an external constant chromomagnetic field is considered. For the case of a weak uniform external field, the one-loop scalar and spinor quark contributions to its antisymmetric component as well as an induced topological photon mass are obtained. Using the instanton field as an example, the P0 in the nonuniform external field case is considered.
