Information recording in three-level systems in external spatially inhomogeneous electric fields with coding of the data in the first two-frequency object pulse is studied. It is shown that when the nonequidistance parameter of the system is <1 the real-time scale in the stimulated photon echo response undergoes changes. When a spatially inhomogeneous electric field is applied between the first and second pulses and after the third pulse, a locking effect is observed in the stimulated photon echo response with an efficiency that depends on the field gradient.
