Active, multi-aperture beam integrator for application adapted laser materials processing

Laser processing applications such as heat treatment require the transformation of the raw intensity distribution into a beam profile of homogeneous intensity. Further the adaption of this profile to altering working geometries results in improved energy coupling and in more efficient material processing. For the utilization of CO2-laser radiation an optical system is developed that both transforms the raw intensity distribution into a homogeneous beam profile and contains the ability to continuously change the spot size independently into two directions.
