Limit values for measuring operation with YAG high div measuring tip
Measuring tips can be operated up to the following maximum power densities:
Power
Maximum power density
Up to 5 kW
10 MW/cm²
Up to 12 kW
8 MW/cm²
Up to 20 kW
6 MW/cm²
Tab. 18.5: Power and maximum power density
The calculations are based on a tophat profile.
The maximum power density in actual beams with the same dimensions is often higher (typically plus 10 %
to 60 %, plus 100 % for a Gaussian distribution). In case of doubt, start with a low laser power.
