Abstract:
A review is given of the papers presented at the Third All-Union Symposium on Optical Echo and Coherent Spectroscopy. The physics of optical transient and superradiant phenomena and the results of applications of these phenomena in spectroscopy were discussed at the Symposium. A new branch of optical spectroscopy is now in existence and it is called coherent spectroscopy. Methods used in this spectroscopy and possible technical applications of these phenomena were discussed in detail at the Symposium.
