Abstract
Correlation of the parameters (delay times, peak intensities) of counterpropagating superfluorescence pulses is studied within the framework of a one-dimensional theoretical model depending on the sharpness of boundaries of the excitation region. The concentration N 0 of the initially excited active centers is described by a smoothed profile (decaying to zero within the h − and h + wide intervals at the left-and right-hand ends of the sample, respectively), rather than by a rectangular profile. It is established that variation of the excitation region boundary widths h ± does not eliminate the observed correlations. Moreover, the correlations can significantly increase for the samples with a length of L=nλ/2, where n is any natural number and λ is the resonance light wavelength. The oscillating dependence of the parameters of counterpropagating superfluorescence pulses on the h ± values and a significant asymmetry of these pulses for h −≠h + are discussed.
