FIELD: physics.
SUBSTANCE: device for monitoring laser engineering processes has a laser with a scanning and a focusing system, narrow-band diode laser, double-channel optical pyrometre, operating in the range from 1.1 to 2.5 mcm, and two video cameras. One video camera records the image of the processing area in the wavelength range from 400 to 950 nm. The other video camera records the image of the processing area either at the wavelength of the laser, or at the wavelength of the narrow-band diode laser.
EFFECT: wider functional capabilities.
