Abstract
For monitoring the working of a workpiece (W) with pulsed radiation of an excimer laser the workpiece surface is periodically illuminated with visible light (B) synchronously with at least some of the laser pulses. A mirror arrangement (S) separates visible light from ultraviolet laser light so that an image corresponding to the working operation can be picked up with a video camera (VK).
