  • Patent number: 10092445
    Abstract: An ophthalmological apparatus includes a base station having a light source generating light pulses, and an application head mountable on an eye having a light projector for focussed projection of the light pulses for punctiform breakdown of eye tissue. The application head has movement drivers moving the light projector in a feed direction and a first scanning direction. A scanner in the base station deflects the light pulses in a second scanning direction. The ophthalmological apparatus includes an optical transmission system transmitting deflected light pulses from the base station to the application head, and superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector in the first scanning direction. Light sources with high light pulse rates, for example femtosecond lasers may be used, without impractical enlargement of the size of the application head.

  • Patent number: 9603743
    Abstract: A device for processing material of a workpiece, the device including a pulsed processing laser, a focusing lens, a beam-deflection unit, a control unit and a confocal detector unit. The intensity of the laser radiation is variable. An imaging unit is provided to detect structures within the workpiece using electromagnetic radiation, wherein the electromagnetic radiation of the imaging unit is radiated via the beam-deflection unit and the focusing lens into the workpiece, and evaluating device is provided and compares the position of the focus of the laser radiation determined by the detector unit with the expected position of the focus in the image of the workpiece obtained by the imaging unit.

  • Patent number: 9162319
    Abstract: The invention relates to a method for removing material by means of a laser, wherein a sequence of laser pulses is generated and an area of material to be machined is irradiated with the sequence of laser pulses. Methods of this kind are used to cut a number of different materials. One problem with this method is that thermal or mechanical damage occurs in the surroundings of the area being machined and causes impairment of areas of material that are not being machined. The invention solves this problem by the pulse energy of a single pulse in the sequence of laser pulses being lower than the laser pulse energy required to produce material removal using an isolated laser pulse in the region irradiated with the single laser pulse of the sequence of laser pulses.
