Abstract
The case of in-process sensing is one of the strengths of laser material processing both in the variety of signals from the process and range of techniques for beam guidance. If the beam could be stabilized at a given location automatically this would be equivalent to relocating the laser beam. Automatic laser beam position sensing is the first step toward this goal. Methods of beam sensing without beam blocking are reviewed and a new device described. This device is based on a beam splitter and a rotating slot.
