Popis: A method for fiber laser output power measurement using a copper-coated optical fiber is proposed. Optical radiation transmitting through the sensor fiber core is partially scattered and absorbed in the metal layer. Its electrical resistance change proportional to the induced heating is measured. The sensitivity can be adjusted by changing the fiber curvature radius. The proposed numerical model of fiber heating was used for intrinsic and bend optical losses coefficients calculation.
