A device for homogenizing a laser-beam profile and a method for focussing and homogenizing a laser beam in laser photocoagulation for coagulating organic tissue, for example in the eye of a living organism.

Device for homogenizing a laser-beam profile

An endoprobe for ophthalmic microsurgery for intraocular treatment of the eye and that affords a surgeon good visibility regardless of the distance from the treatment site in the eye. The endoprobe includes a stainless steel cannula enclosing one or more optical fibers and a laser fiber. A distal end of the optical fibers can be closed by a transparent lens-shaped structure such that an illuminating light transmitted through the optical fibers is radiated and transmitted laser light can exit from the laser fiber, or such that the laser fiber is embedded in a transparent shaped element. The laser fiber may have a covering for transporting light. The laser light may be injected directly into the laser fiber and the illuminating light is injected via at least one optical element into the covering of the laser fiber or into the transparent shaped element.
