20100253937 | MEASURING DEVICE FOR MEASURING A FOCUSED LASER BEAM - According to an embodiment, a measuring device for measuring a laser beam comprises a magnification lens system with a total of two lenses which are arranged in series in the beam path of the laser beam and whose foci are coinciding, as well as a camera which is arranged behind the two lenses in the focus of the last lens and includes an electronic image sensor which generates an electronic image of the magnified laser beam. The lenses together with the camera are adjustable along the beam path relative to a reference point of the measuring device, for the purpose of locating the beam waist of the laser beam and of determining a diameter profile of the laser beam. The measuring device further comprises an adapter enclosing the beam path for coupling the measuring device to a laser system which provides the laser beam. The adapter forms an abutment surface or the laser system, which is axially directed with respect to a beam axis of the laser beam, and permits the measuring device to be coupled in situ at the installation site of the laser system. | 10-07-2010 |

20110190741 | Coupling of an eye to a laser device - According to an exemplary embodiment, a process for coupling a mechanical interface unit to a suction-ring unit retained on an eye by suction force includes a step of relative approximating of the interface unit to the suction-ring unit in an axial direction as far as a first, predetermined relative position of the two components, which is preferentially detected by suitable sensorics. When the first relative position is attained, the evacuation is begun of a suction chamber formed between the interface unit, the suction-ring unit and the surface of the eye, whereby the partial vacuum generated establishes in the suction chamber a contact between the surface of the eye and an applanation plate retained on the interface unit, or enlarges a region of existing contact. The aspirating of the eye onto the applanation plate prevents compression loads and shear loads on the eye such as normally cannot be avoided when impressing the plate onto the eye. | 08-04-2011 |

20120080586 | Process for testing a laser device - 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. | 04-05-2012 |
20120080617 | Production process for an interface unit and a group of such interface units - 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. | 04-05-2012 |

20120206720 | METHOD AND DEVICE FOR EXAMINING A LASER SYSTEM - 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. By evaluating the measured power of the frequency multiplied radiation, dynamic impairments of focusability can be detected, which can be caused by inertia-induced deformations of optical scan components of the laser system. | 08-16-2012 |
