Inverse noise radiation in an active resonance medium
Abstract
The paper considers statistical characteristics of radiation in the resonant medium which propagates towards the side opposite to the direction of the pump wave propagation. It is shown that under the definite conditions the noise radiation spectrum has the maximum which is independent of the pump field. The dependence of the frequency of the radiation maximum on the pump field value is found. The spectral characteristics of radiation propagating in the resonant absorbing medium are analyzed.
