| Zusammenfassung | High power lasers in the kW-power range are nowadays widely used in industrial applications like cutting, welding, melting and hardening. In this presentation we report on the measurements of laser diode power of fibre coupled diode laser radiation at 1065 nm in the multi-kW power range. The calibration setup, the standard detector, the uncertainty budget and first results will be presented and discussed. By using transfer detectors with spectral independent responsivity, traceability also for laser power measurements for other industry-relevant lasers in the 1-μm spectral range (Nd:YAG, Yb:YAG, Yb-fibre) is established. |
