    Abstract: The invention relates to a method of producing microbore holes in a multi-layer substrate (5), especially a printed board substrate which is displaced below a writing optics (4) by means of an XY plate (6), using said optics to generate a spot of a light source (1), especially a laser. The aim of the invention is to reduce the treatment time and preferably to compensate for advantages of the material of the substrate. To this end, the position of the spot within a working field is changed simultaneously with the treatment positions by means of electronically controlled, movable mirrors. The position of the substrate is specifically determined by means of an interferometer (9, 11) and the signals that correspond to the substrate position are processed to an actual position of the table system by means of a suitably equipped processing unit (16). Said processing unit (16) is preferably provided with all bore hole coordinates and additional information such as bore hole diameter, especially in a tabular form.

    Abstract: A beam delivery system for a laser emitting at a relevant wavelength of less than 200 nm is provided. The system includes a sealed enclosure connected to the laser and surrounding the path of the beam as it exits the laser resonator. The enclosure extends between the laser output coupler and a photodetector sensitive at the wavelength of the relevant laser emission. The interior of the enclosure, and thus the beam path between the output coupler and the detector, is substantially free of species that strongly photoabsorb radiation at the relevant laser emission wavelength. A beam splitting element diverts at least a portion of the beam for measurement by the detector. The beam splitting element preferably includes a beam splitting mirror, holographic beam sampler or diffraction grating. In addition, optics are preferably provided for filtering a visible portion of the diverted beam, so that substantially only a VUV portion of the diverted beam is received at the detector. The filtering optics preferably include a diffraction grating, holographic beam sampler or one or more dichroic mirrors.

    Abstract: A technique for marking pixels on workpieces by routing a scanned beam to different markings stations to mark individual pixels on selected ones of the workpieces. Angular position of a scanning mirror in a raster scanner is determined by moving a beam, reflected from the scanner, across rulings on an optical element during scanning. A print head for printing spots on a surface of a workpiece has a walled, internally pressurized chamber with an external curved surface and structure for causing an inked web to conform to the contour of the external curved surface and to be pulled along the external curved surface. Two workpieces may be marked at two marking stations by two-directional scanning.

    Abstract: An apparatus that enables real time measurement of the spatial profile, circularity, centroid, astigmatism and M2 values of a laser beam generated by a high power laser beam. The apparatus employs the optics used in a process application, including a focus lens and cover glass. An attenuation module includes a pair of high reflecting mirror plates disposed in parallel, spaced apart relation to one another at a common angle of incidence to the laser beam. A beam dump is positioned out of a path of travel of the laser beam and in receiving relation to light reflected by the first and second mirrors. A camera detects spots of light that pass through the first and second mirrors. A high power attenuator formed by a highly reflective mirror pair is positioned between the source and the attenuation module. A second embodiment includes a single mirror plate having highly reflective surfaces.
