20130011107 | METHOD FOR MANUFACTURING A PREFORM AND PREFORM FOR DRAWING A MICROSTRUCTURED OPTICAL FIBER - In a method for manufacturing a preform for drawing a microstructured optical fiber, a core element and multiple sub-elements are arranged extending along the perform. The sub-elements and the core element form a bundle, which is twisted by a specified angle about the longitudinal axis of the bundle, wherein the pattern formed by the cross section of the sub-elements and the cross section of the core element is preserved along a length of the perform. The sub-elements and the core elements are subsequently at least partially fused together by heating the material of which the core element and the sub elements are made of above the transformation point of the material, so as to at least partially eliminate the cavities between the sub-elements, between the sub-elements and the core element, and between the sub-elements and the casing. | 01-10-2013 |
20130131657 | APPARATUS FOR MEDICAL TREATMENT OF TISSUE BY MEANS OF LASER LIGHT - An apparatus for medical treatment by means of laser light includes an optical conducting fiber which has a curved light emission end and includes a core, a cladding arranged above the core for conducting laser light coupled into the optical conducting fiber, and capillaries arranged in the cladding, wherein the capillaries run in a longitudinal direction of the optical conducting fiber at a radial distance from a longitudinal axis of the optical conducting fiber and form a capillary ring when viewed in cross-section, wherein the capillaries have cavities which are separated by bridges which have a width which is smaller than a wavelength of the laser light, wherein the laser light emerges from a forward surface of the light emission end and is transmitted in a direction which runs transverse to a substantially straight longitudinal section located directly in front of a curvature which defines the curved light emission end. | 05-23-2013 |
