Reverse Photon Echo as a Method of Investigation of Resonant Medium Parameters
В. А. Зуйков, В. В. Самарцев
The possibilities of the reverse photon echo for obtaining information about the relaxation times and the electrical dipole momentum of the resonant transition are investigated experimentally in ruby (resonant transition 4A2–2E(Ē)). A new method based on the many-pulse excitation of the resonant system by a single travelling wave and by a sequence of standing waves, is proposed. As a result, this system irradiates a series of reverse echo signals, from the decay of their intensities it is possible to define the relaxation times in a single series. These relaxation times are measured at different values of the permanent magnetic field. The different apparatus solutions of these experimental problems are discussed.
