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.

Abstract: The invention provides a cochlea stimulator for implantation comprising optical fibers of which are coupled to an irradiation source that is controlled by a modulator to generate irradiation specific for a pre-determined range of sound-frequencies. The cochlea stimulator effects a frequency-specific activation of the organ of Corti needed for speech perception especially in noisy environment and more complex sounds. For imparting excitation signals which are generated by modulated pulsed laser irradiation conducted within an optical fiber in order to elicit nervous signals in residual functional organ of Corti sections, the auditory prosthesis preferably contains optical fibers which are dimensioned to terminate in end sections within the cochlea at different sites or sections of the organ of Corti. e.g. having different lengths for locating their end sections at different internal parts of the cochlea.

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.
