“…In contrast to this, Schmid et al [2] observed identical pulses in experiments on 0;-centres in KCl crystals. This symmetry was also found by Andrianov et al [3] in pyrenedoped diphenyl crystals. The effect cannot be attributed to reflection at the crystal surface because in the experiment it was made sure that the excited volume was not perpendicular to any surface [2].…”

In superfluorescence (SF) with pencil-shaped excitation volume, two pulses are emitted in opposite directions. While the two pulses are independent in all known gas experiments, they are found ta be strongly correlated in some solid-state systems. A model, in which a distributed-feedback (DFB) structure is formed starting from density fluctuations of the SF centres, is shown to explain the correlation between the counterpropagating waves.

The influence of crystal symmetry on the polarization properties of two-colour optical superfluorescence in biphenyl crystal with pyrene is investigated both theoretically and experimentally. It is shown that polarization of superfluorescence signal is determined by the asymmetry between absorbtion and emission spectra of pyrene molecules in biphenyl, which results in polarization decoupling of pumping and superfluorescence pulses.

“…It is known that an ensemble of atoms or molecules can emit superradiant electromagnetic pulses due to atomic interactions through the common radiation field [1][2][3][4][5][6][7][8][9][10][11]. This type of coherent emission, where the process starts with spontaneous atomic radiation, was first described by Dicke [12] and is often called Dicke superradiance [13].…”
