METHOD FOR MEASURING PARAMETERS AND CHARACTERISTICS OF RADIATION SOURCES Russian patent published in 2023 - IPC G01J1/16 B23K26/02 B23K26/06 

FIELD: laser testing equipment.

SUBSTANCE: method involves placing a laser radiation receiver in the irradiated area of the source under study, then calibrating the reference plate by creating on its working surface a series of spots with different energies in the laser pulse and the same number of laser pulses and simultaneous movement of the reference plate in the horizontal plane so that between the spots on its surface there was the same distance and they did not overlap each other, measuring the area of the spots on the surface of the reference plate at the corresponding specified values of the energy densities of laser radiation pulses, irradiating the working surface of the test sample with the specified energy densities of the source pulses, the spatial position of which corresponds to the position of the plane of the reference plate, comparing the energy of laser radiation from the source, measured by the laser radiation receiver, and the area of the corresponding spots, finding the real area of the laser beam and determining the energy density of the laser radiation.

EFFECT: increasing the accuracy of determining the energy density of a laser radiation source by eliminating the influence of the physicochemical properties of the materials under study on the size of the laser spot area.
