  • Publication number: 20120244032
    Abstract: In order to produce a coating on a substrate, the substrate is placed adjacent to a target. Material is cold ablated off the target by focusing a number of consecutive laser pulses on the target, thus producing a number of consecutive plasma fronts that move at least partly to the direction of said substrate. The time difference between said consecutive laser pulses is so short that constituents resulting from a number of consecutive plasma fronts form a nucleus on a surface of the substrate where a mean energy of said constituents allows the spontaneous formation of a crystalline structure.

  • Publication number: 20100314364
    Abstract: The present invention relates generally to optical scanners. The invention has advantageous applications e.g. in the field laser technology, such as coating and machining with cold ablation technology. An optical scanner according to the invention has a rotating mirror (210), and the reflecting surface (214) of the mirror has an angle in relation to the axis of rotation (216), which varies as a function of the position in the mirror. This way it is possible to provide an optical scanner without discontinuation points and an accurate scanning speed throughout the scanning area.
