Abstract:
1. An ophthalmic laser apparatus for ablation of corneal material and cutting of ocular tissue of the living eye, the apparatus comprising components for providing a first pulsed laser beam having first beam properties matched to the ablation of corneal material and for providing a second pulsed laser beam having second beam properties matched to the making of an incision in the ocular tissue, the components including separate laser-sources for generating the two laser beams and also a plurality of optical elements which guide the two laser beams on separate beam paths to a respective beam exit location and focus them to a focal point situated outside the beam exit location, wherein the optical elements include an optical waveguide serving for guidance of the second laser beam, in that at least the two laser-sources are accommodated in a common housing, and in that the optical waveguide extends within the housing at least over a part of its length; wherein the first laser-source is an excimer laser and the second laser-source is a fibre laser, wherein the second laser-source is arranged in the housing beneath the first laser-source and the optical waveguide is guided upwards within the housing from the second laser-source laterally past the first laser-source, wherein the housing exhibits a base part, provided for the purpose of mounting on a horizontal mounting surface and including a bottom of the housing, and a housing arm projecting transversely from the base part at a vertical distance from the bottom of the housing, and in that the two laser-sources are accommodated preferentially above one another at least mainly in the base part of the housing and at least some of the optical elements are accommodated in the housing arm.
