Lidar diagnostics of ionosphere precipitations

Abstract

Lidar is considered as an electron energy detector of ionosphere precipitations, and the cleaning of radiation belts is like the energy pumping of the ionosphere layer. The excitation efficiency of ionosphere plasma components by precipitations and the features of resonant backscattering of laser radiation in the active ionosphere are discussed. It is shown that in the quantum system in which the lidar plays the role of a master oscillator and the ionosphere layer of the amplifier, different modes of nonlinear oscillations are possible depending on the intensity of the precipitation. Analogies are being made with other natural nonlinear systems.
