Instrument for Measurement of High Levels of Average Radiation Power of Fiber Laser

A design of a flow-through instrument for measurement of the average power of the radiation of fiber lasers is considered. The radiation of these lasers is characterized by an average power of up to 3–4 kW and density up to 3 kW/cm 2 . The measuring instrument does not require complex water treatmen...

Description
Summary:A design of a flow-through instrument for measurement of the average power of the radiation of fiber lasers is considered. The radiation of these lasers is characterized by an average power of up to 3–4 kW and density up to 3 kW/cm 2 . The measuring instrument does not require complex water treatment systems. Devices for absolute measurements of flow rate and water temperature at the inlet and outlet of the instrument along with devices for absolute measurements of the parameters of the electrical current and voltage in regular electrical calibration are incorporated into the instrument.
