Development and Research of Metrological Characteristics of Secondary Standard of Average Power and Energy of Laser Radiation Units

The object of study is the State Secondary Standard of Average Power of Laser Radiation Unit in the range from 10-15 to 10-3 W and in the spectral range from 0.4 to 1.1 μm. The purpose of the work is to select possible schemes for constructing a State Secondary Standard of Average Power of Laser Radiation Unit in the range from 10-15 to 10-3 W and in the spectral range from 0.4 to 1.1 μm, to conduct theoretical studies of the metrological characteristics of the developed standard, to analyze the budget of measurement uncertainty laser power. In this paper, I investigated the setup for measuring the power of low-level laser radiation to study their metrological characteristics. The choice of the design of the developed Secondary Standard of Average Power of Laser Radiation Unit is substantiated. The analysis of the budget of measuring uncertainty of the power unit of laser radiation in the range from 10-15 to 10-3 W and in the spectral range from 0.4 to 1.1 μm has been carried out.
