Abstract
A protective device and method for producing bores, especially very small bores, that open out into a hollow space in a tubular component are provided. The protective device is embodied as a hollow body that is at least partially energy reducing for laser beams. Pursuant to the method, the wall of the component is perforated with a laser beam to produce the bore. After perforation of the wall, the energy of the laser beam is reduced within the hollow space of the component to such an extent that the laser beam does not damage the wall of the hollow space that is disposed across from the produced bore.
