We develop a theory of complex powers of the generalized Klein-Gordon-Fock operator
$$ m^2 - \square - i\lambda \frac{{\partial ^2 }} {{\partial x_1^2 }},\lambda > 0. $$
. The negative powers of this operator are realized as potential-type integrals with nonstandard metrics, while positive powers inverse to negative ones are realized as approximative inverse operators.
