摘要：
A gauge invariant formulation of the so-called intense-field Keldysh-Faisal-Reiss (KFR) approximations in the "velocity" and "length" gauges is given and their equivalence is demonstrated term by term to all orders of the theory. It overcomes a long standing discrepancy between the velocity and the length gauge strong-field KFR amplitudes for nonperturbative processes in intense laser fields.
