Meter of large average power levels of fiber lasers radiation

In this paper, we consider a circuit-based solution for a flow-through measurement of the average radiation power of fiber lasers at levels up to 3-4 kW and a density of up to several 3 kW/cm 2 . The meter does not require the use of complex water treatment systems and the use in the meter of means of absolute flow and water temperature measurements at the inlet and outlet of the meter, as well as the parameters of the electric current and voltage when it is electrically calibrated.
