The paper investigates single-photon superradiance at cyclotron resonance in an ideal single-crystal semiconductor p-type film with a cubic structure placed in a homogeneous static strong magnetic field perpendicular to the film surface. The analysis is performed at a low temperature, when the holes density is maxi-mum at the Landau level n = 0 and is zero at the Landau level n = 1. Using the Lindblad equation for the density matrix, we calculated the current density in the film and the parameters of the electromagnetic field radiated by the film as a function of the electric field strength. It is shown that at the saturation mode when the electric field strength is high the universal loss power per unit area of the film depends only on the fundamental constants c, qe, me and on the induction of the magnetic field.
