The dynamical lorentz shift in an extended optically dense superradiant amplifier.
We compute the spectral distributions of the transmitted and reflected signals from an extended optically dense superradiant amplifier. We show that, if the amplifier length is in the neighborhood of an integer multiple of the resonance transition half-wavelength, the frequency shift in the spectral distributions of the transmitted and reflected signals are modified by the Dynamical Lorentz Shift. The broken spatial inversion symmetry, manifested through an asymmetrical distribution of the population difference with respect to a spatial inversion around the midpoint of the sample, is shown to be at the origin of this spectral asymmetry in these so-called asymmetrical transition domains.
