Metrological Assurance of Laser Measuring Systems

Currently laser measuring systems and sets, interferometers and other measuring instruments the principle of which is based on the use of stabilized laser radiation sources are widely used in metrological laboratories of leading enterprises of various industries and in leading scientific institutes. This report substantiates the need for ensuring the traceability of these measuring systems to the State Primary Standard of the unit of length - metre. Also this report describes the methods for transferring the unit of length to laser radiation sources in the range from 500 to 1050 nm.
