A high resolution, high speed laser drilling system for operating on an advancing product operates to advances the product in a predetermined product advancement path at a product advancement speed. A laser-generating source provides a pulsed laser beam having a laser-on time and a laser-off time. The laser beam is reflected to direct a focal point of the laser beam onto the advancing product. The focal point of the laser beam is moved in a direction of the product advancement path during the laser-on time and is moved in a direction opposite to the direction of the product advancement path during the laser-off time. The system is therefore able to improve laser drilling resolution for a given product advancement speed.

An apparatus and method for high speed laser perforation of a web involves a web-bearing cylinder receiving the web in a wrapped spiral pattern. The web-bearing cylinder includes a slit along a circular circumference of the cylinder. A laser guiding tube is provided for propagation of a laser beam within the web-bearing cylinder. An inner cylinder is also provided in the web-bearing cylinder. The inner cylinder has an axis, supports a reflecting mirror adjacent to the laser guiding tube to direct the laser beam in the slit in the web-bearing cylinder, and is rotatable around the axis to adjust an orientation of the reflecting mirror so as to direct the laser beam around the circular circumference of the web-bearing cylinder in the slit.

An apparatus which selectively directs cutting debris in selected directions while a laser beam separates a workpiece in a multi-directional relation. The apparatus comprises a positionable member rotatable about the laser beam, a nozzle attachable to the positionable member, and a programmable logic controller integrated with the positionable member to selectively position the direction of the nozzle.

A reflective collimator adjusts an input light beam producing an output light beam parallel to the input light beam. The input light beam is reflected and focused by a first reflector to a second reflector, then reflected from the second reflector to a third reflector, and reflected from the third reflector to a fourth reflector, and finally reflected and focused from the fourth reflector to a focus point.

A laser beam delivery system transmits a laser beam with sufficient power to heat treat a work surface. The laser beam is reflected and focused by a first reflector to a second reflector and then onto the work surface. The second reflector is mounted angularly to a rotatable shaft such that when the shaft is rotated, the second reflector rotates about a first optical axis which is separate from a second axis or shaft and at a frequency that produces an integrated energy ring that remains coupled.

A mechanism and method for cutting multiple sheets of fabric by a laser beam and removing the smoke and debris from the fabric. The multiple layers of fabric are disposed upon a honeycomb structure that is secured to a vacuum table connected to a vacuum source where the structure includes a plurality of vertically extended openings through which a laser beam is aimed and focused to cut a pattern in the multiple layers of fabric exclusing any impermeable sheets that cover the fabric above and below the fabric. By eliminating the impermeable sheets, the movement of the airstream is directed to flow towards the laser beam and take with it, the smoke and debris from the multiple layers of fabric. When the airstream is directed generally through the opening in the fabric, it assumes a path that moves substantially parallel to the laser beam.

In a first embodiment, the apparatus comprises a positionable member rotatable about the laser beam, a nozzle attachable to the positionable member, and a programmable logic controller integrated with the positionable member to selectively position the direction of the nozzle. In a second embodiment, the apparatus comprises a plurality of stationary nozzles positioned about the laser beam, a gas source connected to each nozzle, and a programmable logic controller integrated with the gas source to selectively provide a stream of gas to each nozzle and direct the cutting debris in selected directions.

An adjustable beam splitter includes a pentaprism type reflector unit including a housing, a splitter mirror positioned in the housing for transmitting a portion of an input energy beam and for reflecting a portion of the input energy beam, and a reflective mirror mounted within the housing for directing the reflected portion of the input energy beam at a fixed angle to the input energy beam regardless of the angle of incidence of the input energy beam to the splitter mirror and regardless of manufacturing tolerances of the splitter mirror. Translation of the reflected portion of the input energy beam is reduced and the split ratio adjusted by rotating the pentaprism type unit about a line corresponding to the intersection of a plane containing the splitter mirror and a plane containing the reflective mirror.
