Investigation of the mechanism of broadening of resonance lines in ruby by the photon echo method
Kopvillem U.Kh., Nagibarov V.P., Pirozhkov V.A., Samartsev V.V., Usmanov R.G.
From an analysis of the experimental dependence of the photon echo on the polarization, contour, and propagation directions of the exciting pulses, on the intensity of the constant magnetic field, and on the time τ between the pulses, it is found that the decisive contribution to the damping of the echo in the ruby, at a Cr3+ ion concentration ~0.1 at.%, is made by magnetic dipole-dipole interactions. It is established that this damping is determined by the exponential — exp(—A Vt), where A is a damping constant corresponding to the magnetic dipole-dipole interactions.
