<p>A high resolution, high speed laser drilling system (30) for operating on an advancing product operates to advances the product in a predetermined produc t advancement path at a product advancement speed. A laser-generating source (12) provides a pulsed laser beam (14) having a laser-on time and a laser-of f time. The laser beam is reflected to direct a focal point of the laser beam onto the advancing product (18). The focal point of the laser beam (14) is moved in a direction (36) of the product advancement path during the laser-o n time and is moved in a direction opposite to the direction of the product advancement path during the laser-off time. The system (30) is therefore abl e to improve laser drilling resolution for a given product advancement speed.< /SDOAB></p> |
