Abstract

Various applications of lasers are based on the use of data on the distribution of the power density (energy) in the cross section of the beam in the near and far zones. The distribution of the power density (energy) of the laser beam is characterized by a spatial distribution, which is obtained experimentally with a transverse displacement in a certain isolated plane perpendicular to the direction of propagation of the radiation. In this paper, we measured the distribution of the power density (energy) of laser radiation in a cross section with the z coordinate by placing the MKT-1 receiver with a sufficiently high spatial resolution directly in the beam. A model is constructed for estimating the uncertainty of the results of a laboratory experiment. The combined uncertainty of type B for the coordinate (-4;0), which is . For the confidence level P = 95 %, assuming that the possible measurement results are distributed according to the normal law, an expanded uncertainty is defined. As a result, graduate students (PHD) will get acquainted with the new terminology used in the control and measurement procedure, as well as estimate the uncertainty based on the experimental measurement of the power density (energy) distribution of laser radiation.
