Adaptive regulation of the spectral component of the radiation power of a multiwave laser system

This article presents a method for increasing the energy efficiency of systems using laser radiation for information transmission by automatically selecting a rational radiation power. A model of the process of adaptive adjustment of the spectral component of the radiation power of a multiwave laser system has been developed based on the analysis of the magnitude of the optical signal reflected from the retroreflector in order to ensure the required level of laser radiation power for reliable information transmission by each separate channel. In the software environment MATLAB Simulink, on the basis of the mathematical apparatus of the theory of automatic control, an imitation of the process under study was made and the adequacy of the proposed model was confirmed. The model implies the possibility of its correction by changing the amplifying and inertial properties of the circuit elements to describe particular cases of the functioning of a multiwave laser system.
