Ensuring Stable Processing with High-Power Continuous Wave Lasers through Targeted Beam Analysis

Powerful, yet sensitive: High-power laser beams are easily disturbed before reaching the metallic workpiece. Changes in the relevant beam parameters can be subtle, like gradually increasing focus shift, but result in unacceptable part quality.

In this talk, Blumenstein visualizes the most important beam parameters and presents actionable insights on how to track, evaluate, and handle them. This includes the statistical analysis of more than 3000 individual beam caustic measurements which nicely reveals the unavoidable beam degradation through optical guidance systems.
