FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, namely to devices for measuring power of optical radiation, and can be used, in particular, for measurement of optical power of high-power fiber lasers. Device for measuring optical power of fiber lasers, having an optical element, which is transparent in the spectral range of the measured radiation. Optical element is a fiber light guide with a metal coating, wherein the metal coating is connected through electrical contacts to an electrical resistance meter.
EFFECT: high accuracy when measuring power of laser radiation.
