high power measuring tip
Measuring tips can be operated up to the following maximum power densities:

Maximum power density
Up to 6 kW
30 MW/cm²
6 kW bis 12 kW
20 MW/cm²
Up to 20 kW
15 MW/cm²
Tab. 18.3: Power and maximum power density
The calculations assume a Gaussian profile.
The maximum power density in real beams with the same dimensions is often slightly smaller (typically minus
10 – 20%, minus 50% for a tophat distribution). In case of doubt, start with a lower laser power.
