Abstract

A laser device (10) for material processing, in particular for laser processing of a human eye (12), comprises a source (14) of a pulsed laser beam (16), a detector system for the photodetection of a plurality of partial beams (16', 16'') generated from the laser beam by radiation outcoupling and provision of corresponding detection signals, and a control unit (24) linked to the detector system for evaluating the detection signals. A first detection signal is provided by a first detection element (32) of the detector system, which signal is based on single-photon absorption. A second detection signal is provided by a second detection element (34) of the detector system, which signal is based on two-photon absorption. In certain embodiments, the control unit puts the measured signal strengths of the two detection signals into a ratio to one another. Assuming a uniform pulse repetition rate of the laser beam (16) and an unchanged average power of the laser device, variations in the resulting ratio value can then be traced back to variations in the pulse duration or/and wave front of the laser beam 16. The beam quality of the laser beam can be maintained during the emission operation of the laser device in that the control unit initiates suitable countermeasures.

Abstract

A method and system for instantaneous time domain optical coherence tomography (iTD-OCT) provides instantaneous optical depth profiles in an axial direction to a sample having scattering properties or that is at least partially reflective. An iTD-OCT instrument includes a spectroscopic detector having an internal optical axis and an array of detector pixels. A reference beam having a fixed optical path length is superpositioned along the optical axis with a measurement beam that includes back-scattered photons from the sample. The detector pixels capture a time domain interference pattern arising within the spectroscopic detector due to optical path length differences between photons from the reference beam and photons from the measurement beam. The iTD-OCT instrument may be implemented as a robust solid-state device with no moving parts.

Abstract

A method for energy setting of pulsed, focused laser radiation is provided. In the method, a relationship between a threshold pulse energy required for causing irreversible damage in a material and a pulse duration is established. The relationship allows to obtain a threshold pulse energy for each of a plurality of pulse durations including one or more pulse durations in a range between 200 fs and smaller. The relationship defines a decreasing threshold pulse energy for a decreasing pulse duration in the range between 200 fs and smaller. For a given pulse duration in the range between 200 fs and smaller, an associated threshold pulse energy is determined based on the established relationship. The pulse energy of the laser radiation is set based on the determined associated threshold pulse energy. In certain embodiments, the relationship represents a decrease of the threshold pulse energy substantially as a function of the cubic root of the pulse duration.

Abstract

Embodiments of the invention provide a method and apparatus for laser-processing a material. In the method and apparatus, a diffraction-limited beam of pulsed laser radiation is diffracted by a diffraction device to generate a diffracted beam of pulsed laser radiation. The diffracted beam is subsequently focused onto the material and is controlled in time and space to irradiate the material at a target position with radiation from a set of radiation pulses of the diffracted beam so that each radiation pulse from the set of radiation pulses is incident at the target position with a cross-sectional portion of the diffracted beam, the cross-sectional portion including a local intensity maximum of the diffracted beam. The beam cross-sectional portions of at least a subset of the pulses of the set include each a different local intensity maximum. In this way, a multi-pulse application for generating a photo-disruption at a target location of the material can be implemented.

Abstract

A method for preparing an endothelial corneal graft is provided. The method com¬ prises: providing a donor cornea; irradiating the donor cornea from an endothelial side thereof with laser radiation to cause a photodisruption in tissue of the donor cornea at a focal point of the radiation; and moving the focal point of the radiation to form an endothelial graft in the donor cornea. By irradiating the donor cornea from the endothelial side thereof, instead of the epithelial side, to cut the endothelial graft, optical inhomogeneities which may develop after death in stromal tissue of the donor cornea leave the laser cutting process substantially unaffected.

An interface device is coupleable to the laser apparatus and has an applanation element comprising a front surface and a back surface. A laser beam having a predefined shape is focussed through the applanation element at a focus point. A superimposed image of a spurious reflection, which is reflected from the front surface of the applanation element, with a standard reflection, which is reflected from the back surface of the applanation element, is detected. The spurious reflection is then filtered out of the superimposed image. Based on the remaining standard reflection, the depth of the focus point of the laser beam can be determined.

The control program provides, for each plane, a meandering scan path that, at least in the region of the reversing-points, extends outside the tissue volume. Furthermore, the control program is designed to allow, in each plane, at least such radiation pulses which serve for generating the first incision. Said control program is also designed to blank, in at least a fraction of the planes at least a fraction of those radiation pulses which are assigned to regions of the meandering scan path that are situated at a distance from the first incision.

Abstract

The invention relates to a method for examining a laser system (10), which has a focused laser beam (141) and a controllable deflecting arrangement (18) for transversely and/or longitudinally controlling the location of the beam focus, comprising the steps of directing the laser beam or a sub-beam therefrom that has been bifurcated after the deflecting arrangement onto an optically non-linear medium (26) in order to generate frequency-multiplied radiation (14"), the wavelength of which corresponds to a non-linear higher harmonic of the wavelength of the laser beam, activating the deflecting arrangement (18), and measuring a power of the frequency-multiplied radiation while the deflecting arrangement is activated. The conversion efficiency of the non-linear process by which the frequency-multiplied radiation is generated depends on the ability to focus the laser beam (141). By evaluating the measured power of the frequency-multiplied radiation, dynamic impairments of the ability to focus, which can be caused by the deformation of optical scanning components of the laser system due to inertia, can be detected.

Abstract

According to an exemplary embodiment, a method for coupling a mechanical interface unit (34) to a suction ring unit (16) that is held on an eye by suction force comprises a step of bringing the interface unit relatively closer to the suction ring unit in an axial direction, into a first predetermined relative position of the two components that is preferably detected by suitable sensors. When the first relative position is reached, the evacuation of a suction chamber (42) formed between the interface unit, the suction ring unit and the surface of the eye is commenced, the negative pressure produced in the suction chamber establishing a contact between the surface of the eye and an applanation plate (40) held on the interface unit, or increasing the size of a region of existing contact. The sucking of the eye onto the applanation plate prevents the eye from being subjected to compressive and shearing stresses such as those that are often unavoidable when the plate is pressed against the eye.
