In order to measure rapid power changes in the laser radiation, the device is designed in such a way that a device is provided for integrating locally the laser radiation, and at least a further detector is connected to the said device in addition to the thermal detector, permitting the measurement of radiation power changes of greater bandwidth than the bandwidth detected by the thermal detector and that a circuit for combining the measurement signals of the detectors is divided.de608621patent1988-3820619
