Ensuring the Uniformity of Measurements of Spatial-Energy Characteristics of Pulsed Laser Radiation

The structure and principle of creation of a standard for the spatial-power characteristics of pulsed laser radiation are examined, and problems solved with its aid are enumerated. Measurement results of spatial-energy characteristics (beam width, angle of divergence, centroid coordinates) of pulsed...

Description
Summary:The structure and principle of creation of a standard for the spatial-power characteristics of pulsed laser radiation are examined, and problems solved with its aid are enumerated. Measurement results of spatial-energy characteristics (beam width, angle of divergence, centroid coordinates) of pulsed laser radiation are presented. Errors of conversion of the units of width and angle of divergence of the laser beam, as well as the total error of the standard, are estimated.
