Abstract: Within the framework of parameterized post-Maxwellian vacuum electrodynamics, the propagation of an X-ray and gamma radiation pulse through the electromagnetic field of a relativistically rotating pulsar is investigated. Expressions are obtained for the trajectory of this pulse and for the law of its motion from the point where at the moment of time an X-ray or gamma-ray burst occurs, to the point where the detector of this radiation is located. In the case when the post-Maxwellian parameters of the theory differ,, the time of nonlinear electrodynamic delay of electromagnetic signals carried by different normal modes is calculated. The change in the polarization state of the X-ray or gamma radiation pulse after passing through the electromagnetic field of a relativistically rotating pulsar is analyzed. The possibilities of observing the nonlinear effect of the electromagnetic field of a relativistically rotating pulsar on X-ray and gamma-ray pulses are discussed.
