N. G. Basov (EDT) Coherent Cooperative Phenomena

Annotation

This anthology is devoted to the theoretical and experimental study of coherent phenom- ena in quantum optics. Considerable attention is devoted to the investigation of cooperative effects in multilevel molecular and atomic systems. The theoretical analysis is based on a single approach, using the theory of groups, which makes it possible to present the results in a compact and physically elegant form. The results of a detailed experimental and theoretical investigation of the photon echo, self-induced transparency, and nutation are presented. The theory of a coherent resonant mechanism for the interaction of laser radiation with multi- atomic molecules which causes "prompt" dissociation is presented. A number of applied pos- sibilities, in particular, the control of radiation by laser light and laser isotope separation, are analyzed. v CONTENTS Coherent Physics and Its Applications. * . . * * . . * . . . . . . . . . . * * * * . . . * . . . . 1 L.
