ABSTRACT:
Plastic well screen has tapered, undercut slots formed by a laser beam focused through a lens having its focal point located at or slightly away from the surface of the plastic cylinder being slotted so that the laser beam diverges as it passes through the plastic. The cylinder is rotated and simultaneously moved axially relative to the laser beam to produce a series of transverse slots. In one embodiment, the laser beam is interrupted to provide continuous longitudinal support portions in the cylinder. In a modified embodiment, the cylinder has integral internal ribs which remain intact even though the laser is operated continuously to remove surface material located between the ribs and the laser beam.
