Abstract
Device for the characterization of a laser beam according to a 'Knife edge' method as defined by Standard ISO 11146. The device has a lens for the focalization of an incident laser beam, and a detector. Interception elements are located between said lens and said detector in order to intercept sequentially the focalized laser beam in a plurality of different positions along its axis of propagation. The interception elements are suitable to allow, in each one of said positions, the passage of a progressively increasing (or decreasing) portion of the vocalized laser beam starting from a condition of substantially total (or null) interception up to a condition of substantially null (or total) interception.
