Abstract: Systems are provided for delivering a calibrated ultraviolet radiation pulse at a treatment plane during a laser-ablation treatment of a patient's eye. Exemplary systems include an ultraviolet radiation source, and a fluorescent plate positioned to receive an initial ultraviolet radiation pulse produced by the ultraviolet radiation source. The fluorescent plate generates a visible light pulse in response to the initial ultraviolet radiation pulse.

Abstract: Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.

Abstract: Embodiments generally describe systems, devices, and methods for focusing and calibrating beam profilers. A test object is provided that may include an internal housing rotatable within an external housing. The internal housing may house a light source, a collimator, a filter, and/or a diffuser. A plate may be mounted to the internal housing and may include a plurality of markings. In some embodiments, to focus a beam profiler, the test object may be positioned adjacent the converter plate of a beam profiler. Marker images may be captured and a focus quality may be assessed therefrom. A position of the converter, objective, and/or camera of the beam profiler may be adjusted based on the focus quality. To calibrate, images of the markings in several rotational positions may be captured and used for calibration. The markings may be rotated to several positions by rotating the internal housing relative to the external housing.

Abstract: A system for extending the operation of a local communications port of a client computer includes a central server, a client communication module, and a remote communication device, each connected to a communication network. A method of operating a central server in a communications network begins with establishing a first communication link between the central server and a remote communication device in response to a request from the remote communication device. A second communication link is established between the central server and a client communication module in response to a request from the client communication module. Application data is received from the client communication module via the second communication link and forwarded, via the first communication link, to the remote communication device. Remote equipment data is received from the remote communication device via the first communication link and forwarded, via the second communication link, to the client communication module.

Abstract: Laser eye surgery systems, methods, and devices makes use of a two-pivot scanning system for laterally deflecting the laser beam across the corneal surface to provide X-Y scanning. An imaging lens pivots about two eccentric axes extending along, but disposed beyond the laser beam. As the lens pivots, the beam will follow a substantially arc-shaped path. The eccentric axes are offset about the laser beam axis by about 90°, and the system controller can compensate for the arc-shaped path deflections by adjusting the angular position of the imaging lens about complementary stage.

Abstract: A corrosion resistant, multi-layer structure on a substrate including an adhesion metallic layer on the substrate, a cushion metallic layer on the adhesion layer, a diffusion barrier layer on the cushion layer, and an impermeable gold layer that encapsulates all the layers, is substantially even on all sides of the layers, and contacts a region on the substrate adjacent the layers to prevent oxidation and corrosion.
