Abstract:
1. A laser system for cutting and identifying multiple stents, comprising: a laser system having a plurality of laser beams generated from an output of a single laser for cutting patterns into a plurality of stents at the same time, with each of the plurality of laser beams being controllable to produce a desired power, polarization and spot size and each laser beam directed at a separate stent work piece; a laser capable of emitting a linearly polarized laser beam; at least one partially transmissive and partially reflective beam splitter capable of dividing the laser beam emitted by the laser into two laser beams; a focusing lens for focusing each laser beam to a desired spot size; a circularly polarized beam spot for each laser beam is controlled to accurately cut through a wall of each stent work piece upon which each laser beam impinges; and a computer controlled locating fixture for moving each stent work piece in a selected manner beneath the laser beam to etch a surface of each stent work piece with identifying information without cutting through the wall of each stent work piece.
