Abstract Highly dynamic drives, e. g., piezo or voice coil drives, enable a high‐frequency deflection of the laser beam on the workpiece surface. Modern solid‐state lasers allow modulation of the specified laser power in frequencies of several kilohertz. If these possibilities are combined strictly synchronously, the result is previously unavailable technological advantage on the component to be processed: the programmable beam quality. Using the example of specific optical and machine solutions, the following describes how these possibilities have been realised for industrial use and proves the technological advantages on application examples in the processes of laser welding and laser powder cladding.
