Эталонный источник средней мощности коллимированного лазерного излучения

Abstract

A technical solution of a source of collimated laser radiation based on the calorimetric principle is realized with the realization of the self-similar thermal regime of its operation with the direct and reverse switching on of the electric supply of the laser diode. The algorithm of the measuring process is proposed which makes it possible to reduce the determination of the radiation power at the source output to an estimate of the difference in the power values of the electric current acting on the diode in these modes inclusion.
