Patent number: 8717547Abstract: A process for producing an interface unit and also a group of such interface units are specified. The interface unit exhibits a first reference surface for beaming in radiation, a second reference surface for emitting the radiation, and an axis extending in the direction from the first to the second reference surface. The production process comprises the steps of setting an optical path length of the interface unit between the first and second reference surfaces along the axis and the fixing of the set optical path length of the interface unit. The optical path length of the interface unit is set in such a way that radiation of a defined numerical aperture beamed in at the first reference surface exhibits a focus location that is predetermined with respect to the second reference surface in the direction of the axis. A precise and uniform focus location with respect to the second reference surface is obtained.Type: GrantFiled: September 30, 2010Date of Patent: May 6, 2014Assignee: Alcon Research, LtdInventors: Claudia Gorschboth, Jing Li, Klaus Vogler, Olaf Kittelmann, Thomas Deisinger, Gerhard Robl

Patent number: 8687178Abstract: A process is proposed for testing a laser device that has been set up to emit pulsed focused laser radiation, the focal position of which is adjustable both in and across the direction of propagation of the laser radiation. The laser device includes a contact element that is transparent to the laser radiation, with an abutment surface for abutment of an object to be machined. Within the scope of the process, a test object that is transparent to the laser radiation at least in a machining region is applied onto the abutment surface of the contact element. Then laser radiation is beamed into the test object bearing against the abutment surface and in the process the focal position is moved in accordance with a predetermined test pattern, in order to generate enduring machining structures in the test object.Type: GrantFiled: September 30, 2010Date of Patent: April 1, 2014Assignee: Wavelight GmbHInventors: Thomas Deisinger, Christof Donitzky, Claudia Gorschboth, Richard Heimisch, Olaf Kittelmann, Gerhard Robl, Martin Starigk, Klaus Vogler, Mathias Wölfel

Patent number: 8665428Abstract: A method for analyzing a laser system, which has a focused laser beam and a controllable deflection assembly for controlling the transverse and/or longitudinal position of the beam focus, said method comprising the steps of directing the laser beam or a partial beam branched therefrom downstream of the deflection assembly toward an optically nonlinear medium for the purpose of generating frequency multiplied radiation, the wavelength of which corresponds to an uneven higher harmonic of the wavelength of the laser beam, activating the deflection assembly, and measuring a power of the frequency multiplied radiation while the deflection assembly is activated. The conversion efficiency of the nonlinear process by which the frequency multiplied radiation is produced is dependent upon the focusability of the laser beam.Type: GrantFiled: November 9, 2009Date of Patent: March 4, 2014Assignee: Wavelight GmbHInventors: Matthias Fösel, Olaf Kittelmann, Klaus Vogler
