  • Patent number: 10327952
    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.

  • Patent number: 10179070
    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.

  • Publication number: 20180078418
    Abstract: A laser pulse energy control system which includes a laser source and a beam divider positioned to receive a calibration laser pulse produced by the laser source. The beam divider reflects a first portion of the calibration laser pulse along a first optical path toward a first plane and transmits a second portion of the calibration laser pulse along a second optical path toward a second plane. An energy meter determines an energy of the first portion of the calibration laser pulse at the first plane and a fluence profiler determines a fluence profile of the second portion of the calibration laser pulse at the second plane. The processor controls an energy of an ablation laser pulse produced by the laser source based on the fluence profile of the second portion of the calibration laser pulse and the energy of the first portion of the calibration laser pulse.

  • Patent number: 9702692
    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.
