Laser myth busting

Abstract

High‐power laser systems are routinely employed as production tools, but the laser beam itself is sensitive to various disturbances, especially in the light of current trends toward extreme power and high beam quality. Suitable tools are available to characterize the process‐relevant beam parameters – from power through focus dimensions to scanner‐imposed properties. Yet either the challenges or the measurement tools tend to be underestimated – justifying a closer look at some of the common myths.
