Device description

4.1 

Device models and options

There are two models of HighPower-MSM-HighBrilliance:

•  HP-MSM-HB and
•  HP-MSM-HB 20 kW 

The HP-MSM-HB is designed for a maximum beam power of 10 kW, the HP-MSM-HB 20 kW for a maxi-
mum of 20 kW. 
The maximum travel distance z

max

 is 120 mm for the 10 kW model and 40 mm for the 20 kW model. 

For the measurement of fiber lasers, the HP-MSM-HB can optionally be equipped with a measuring bridge 
with fiber adapter.
Another option is to measure the laser power with a PowerLossMonitor PLM (additional device).

4.2 

Area of Application

The HP-MSM-HB is intended for the analysis of the focused beam in the diameter range between 20 µm 
up to 1000 µm. In the measuring range the power density distribution can be measured individually in up to 
50 measuring planes. The beam caustic is then made up of these measuring planes. 
The beam geometries (beam position, beam radius and semiaxes – lengths as well as the dumping of the 
semiaxes to the device axes) are determined for each plane according to the procedures described in the 
standard ISO 11146 (2. moment and 86 % power inclusion). By means of these beam geometries the beam 
propagation parameters (focus position, focus radius, Rayleigh length, divergence, M², K and beam param-
eter product) are determined. By means of the measuring data for the semiaxes of the beam, the ellipticity of 
the focus and the astigmatic difference are determined according to ISO 11146.
