  • Patent number: 4553017
    Abstract: Apparatus and method for increasing the power density of an energy beam (e.g. a laser beam) by focusing an incident beam to an anisometric configuration and thereafter focusing the anisometric beam to a modified, preferably isometric, configuration. A serrulate reflective surface facilitates the splitting of an incident beam into a plurality of high energy reflected beams, and the technique is of utility in perforating webs, such as polyolefin films.
