The laser – the beam source – is the central component in all laser processing. In the field of high continuous power, mostly CO2 or NIR lasers (fibre, disk, Nd:YAG or diode lasers) are employed.
For the manufacturers and purchasers of beam sources, approval of these products is of outstanding importance. With the increasing desire for quality assurance, the measurement of beam parameters has now frequently become a fixed component of internal acceptance inspection or commissioning at the client's site. Above all, the following are critical: laser power, beam dimensions and beam position of the raw beam and the focus, and also beam quality.
Laser power meters are used for continuous operation – such as the PowerMonitor, PM or the CompactPowerMonitor, CPM.
The BeamMonitor is available for the investigation of the raw beam. The LaserQualityMonitor enables more detailed statements about beam quality.
For internal acceptance inspection or for acceptance at the customer's site, laser manufacturers employ the combination of FocusMonitor and PowerMonitor.
But the MicroSpotMonitor is also in demand for suitable applications.
It is not only in product acceptance that beam diagnostics provide valuable assistance to beam source manufacturers. When it comes to servicing, the measuring systems plan an important role and help to document the current state.
