The article presents the metrology of high-intensity laser radiation for technological and special equipment. A laser power stabilization system with an output power of 2-1·104 W has been developed and studied. The presented stabilization system makes it possible to reduce the error in the transmission of a unit of average laser radiation power when using a technological laser with an unstable output power as part of the standard. National primary standard for the unit of average laser power GET 28-2022 was approved. Standard includes a laser stabilized in terms of laser power, as well as a reference measuring detector of a thermoelectric type and a measuring beam splitter. The means of transmitting a unit of average power of laser radiation from the range of 1·10-9-2 W to the range of 2-1·104 W, as well as the system for reproducing and transmitting a unit of average power in the range of 2-1·104 W, are studied. In conjunction with the use of the developed industrial laser stabilization system, the power of the laser radiation of the standard was increased from 2 to 1·104 W.
