The principles of monitoring the laser processing of metals are considered; the design and the main parameters of the spectrophotometer designed on the base of an optical-fiber AvaSpec 2048 spectrometer with the spectral range 380–1050 nm are presented. The technique of its calibration is discussed and the obtained spectral sensitivity is reported. The measured spectra of optical and near IR radiation that forms in the contact region of CO2 laser radiation (wavelength 10.2 μm, power 1 kW) with the steel surface are presented. The problems of selecting the spectral portion in which the uncertainty of measuring temperature during contactless technological monitoring of high-temperature laser processes using thermographic devices will be minimal are discussed.
