  • Patent number: 5011282
    Abstract: To automatically align a laser beam path with respect to an axis along which a movable carriage of a laser processing machine moves, the apparatus of this invention comprises means for detecting laser beam position at least when the carriage is positioned at a first and a second position, means for displaying the detected laser beam positions, and means for adjusting the mirror tilt angle. In the apparatus, the laser beam path is aligned with respect to the axis by actuating the mirror tilt angle adjusting means so that the second laser beam position on the display means is moved to coinside with the first laser beam position. The apparatus of this invention may comprise, instead of the display means, means for calculating an inclination angle of the laser beam with respect to the axis, based on the distance between the first and the second position, and distance between the first and the second laser beam position.

  • Patent number: 4653061
    Abstract: The present invention relates to a specific holding structure of a slab geometry crystal for a total internal reflection, slab geometry laser (otherwise known as face pumped laser) device. Both sides of the crystal are held by side rails, and on both longitudinal end portions of the crystal o-ring backing flanges and box-shaped end pieces, respectively, are put on. Furthermore, an o-ring is put in between the end piece and the o-ring backing flange on each end portion of the crystal, and it is compressed to seal the crystal. This o-ring can be made of translucent elastomer. Accordingly, the slab geometry laser device that is compact and easy to remove from, or place into the pump station is provided.
