Abstract
A laser cutting system for cutting articles, such as tubes, and method of using the same. The laser cutting system can cut slots, holes, and/or pores into each article or tube to form filtration tubes, for example. The system includes a delivery system for delivering a laser beam from a laser source, at least one mirror, a focusing objective lens, a gas source, and a delivery nozzle. A first stage holds each article in a longitudinal direction, and may rotate the article axially during delivery of the gas and laser beam towards the article and move the article longitudinally relative to the delivery nozzle. A second stage is provided in the system for moving the delivery nozzle relative to the article being held by the first stage. A controller controls actuation of the laser beam and the gas source, and movement of the first stage and the second stage.
