Metrological ensures for high-power laser radiation

The paper presents the state of ensuring the uniformity of measurements of energy parameters of high-power laser radiation. The research was carried out at the All-Russian Research Institute of Optical and Physical Measurements. The formation of a metrological support system for measuring the energy parameters of high-power continuous laser radiation required the creation of three standards, including one State primary standard of average laser power, and a line of four basic measuring instruments in the spectral range 1.07–10.6 μm and power range 1–500 kW. For the first time, a dynamic method for measuring high levels of laser power was developed and used. This ensured the certification of measuring instruments using reference radiation with a power of less than 100 kW. This has led to a significant increase in the level of metrological support for technological and special high-power laser equipment.
