    Abstract: In certain embodiments, an optical system for obtaining surgical information includes a probe housing a first optical fiber, a light source, a photoanalyzer, and an optical circulator optically coupled to each of the first optical fiber, the light source, and the photoanalyzer. The optical circulator has a first port configured to receive source light generated from the light source, a second port configured to transmit the source light from the first port to the first optical fiber, and a third port configured to transmit return light in the first optical fiber from the second port to the photoanalyzer. The first optical fiber is configured to emit at least a portion of the source light in the first optical fiber from the probe to contact a body structure, and collect light returning from the body structure as a result of the portion of the source light contacting the body structure.

    Abstract: A surgical microscope is configured to capture images of an eye of a patient and defines an optical axis. An illumination source is configured to emit a plurality of beams onto the eye of the patient at a plurality of angles relative to the optical axis. A controller is coupled to the surgical microscope and the illumination source, the controller configured to independently control values for illumination parameters for each beam of the plurality of beams to facilitate imaging of the eye of the patient. The illumination parameters may compensate for reflections from the iris, offset of the eye relative to the optical axis, and reflections of ambient light. The illumination parameters may be controlled subject to inputs received from a surgeon or other user.

    Abstract: A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

    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.

    Abstract: A beam delivery system for a probe includes a plurality of laser sources configured to generate a respective incident beam, including a first laser source generating a first incident beam and a second laser source generating a second incident beam. The system includes routing structures respectively positioned along a path of the respective incident beam. An optical subsystem is adapted to sequentially direct a respective output beam from the routing structures into each core of a multi-core fiber in communication with the probe. The first routing structure and the second routing structure respectively include an array of optical elements adapted to be synchronously moved such that the first incident beam and the second incident beam encounter an identical member of the array at a same time.
