Zusammenfassung:PCT No. PCT/DE89/00402 Sec. 371 Date Feb. 12, 1991 Sec. 102(e) Date Feb. 12, 1991 PCT Filed Jun. 16, 1989 PCT Pub. No. WO89/12806 PCT Pub. Date Dec. 28, 1989.Apparatus for measuring the radiation power of lasers, particularly infrared lasers, with a thermal detector, which supplies a power-caused measurement signal. In order to be able to measure rapid laser radiation power changes, the apparatus is so constructed that there is a device which locally integrates the laser radiation and to which, apart from the thermal detector, is connected at least one further detector, which is able to detect radiation power changes with a larger band width than the band width detectable by the thermal detector and that there is a circuit combining the measurement signals of the detectors.
