Working control system for space-time characteristics of industrial IR lasers

This paper discusses the problem of monitoring emission parameters of lasers in industrial use. The principles of a system for working control and analysis of the space-time characteristics of these IR lasers are considered. The authors explain how the IR emission of a laser is applied to a beam splitter and the component is diverted to the aperture of a shaping optical system that transforms the radiation and separates the investigated radiation parameter. The IR radiation acting on the LS causes heating of the luminor excited by the source. The image on the LS is projected through an optical system that contains a filter opaque to the UV radiation. The output goes to a computing unit and are picked off the radiation-beam parameters needed for monitoring and control.
