Laser Beam Profiling and M² measurement
Laser Beam Profiling and M² measurement

The quality of the radiation is often referred to in material processing and measurement technology. Depending on the application, the quality is determined by the temporal and local stability of the output power, the width of the frequency spectrum, the temporal and local coherence, and the magnitude of the beam divergence, which is related to the extent to which the radiation can be focused.



The Polarization Preserving Beam Sampler (PPBS) uses a dual wedge design to sample a small percentage of a beam’s power for laser beam profiling applications.
