Fabrication and performance characteristics of a thick film laser power detector are presented in this paper. The new sensor combines the advantages of a circular resistor and a highly sensitive NTC resistor paste. As a consequence of the layout, the sensitivity of this sensor depends slightly on the eccentricity and the positioning of the laser beam. Therefore, the measurement of the laser power is more simple, whereas the linearity and the reliability of the detector are of high standard.
