Measurement methods – the principle

FPM is designed to measure solid state lasers with wavelength: 1030–1090 nm. At the beam inlet, an electrical closing device and a protective glass protect the measuring device from contamination. The beam coming from the laser and the processing head is directed into the device via a deflecting mirror. The beam reaches the measuring components via a beam splitter and a further deflecting mirror. The laser power is measured calorimetrically. For this purpose the laser irradiates the absorber for a defined period. With the help of the known heat capacity, the temperature increase in the test body and the irradiation period, the power is calculated. The camera-based beam analysis unit measures the beam geometry and beam position with a CCD sensor. A fieldbus interface lastly forwards the measurement data data to the system controller. An additional PC is not required. Measuring period is typically 0.3 s
