Abstract

The method of elimination of boson operators is used to theoretically analyze the possibility and optimal conditions of superradiance regime of laser cooling of crystals and glasses doped with rare-earth ions. A set of kinetic equations governing the processes of laser cooling and optical superradiance in a multilevel system is derived for the pulsed regime. It is demonstrated that the efficiency of laser cooling in this regime is proportional to a factor N²(lambda) ²Kn_S, where N is the number of active impurity centers, (lambda) is the superradiance wavelength, K is the number of superradiance channels, and n_S is the number of superradiance events per second.
