  • Patent number: 11432963
    Abstract: Particular embodiments disclosed herein provide a surgical laser system comprising first laser source configured to emit a first laser beam with a first wavelength and a second laser source configured to emit a second laser beam with a second wavelength. The surgical laser system further comprises a first diffraction optical element (DOE) tuned to the first wavelength and a second DOE tuned to the second wavelength, wherein the first DOE is configured to diffract the first laser beam into one or more first diffracted beams at a diffraction angle and the second DOE is configured to diffract the second laser beam into one or more second diffracted beams at the same diffraction angle. The surgical laser system further comprises one or more beam splitters configured to reflect the one or more first diffracted beams and the one or more second diffracted beams onto a lens.

  • Publication number: 20220125640
    Abstract: In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals traveling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.

One embodiment of the apparatus can include: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a motor for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame.
