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.

Abstract: The present disclosure relates to a MCF, including a plurality of cores, an outer cladding or tube, diffusion barriers, and claddings. The diffusion barriers and claddings are designed so that unwanted migration of dopants from the inner cladding to the outer cladding or tube is reduced, or that unwanted migration of dopants from the cores to the outer cladding or tube is reduced. The doping levels of the various components of the MCF can be controlled in order to reduce dopant migration. The reduction in dopant gradients reduces the migration of dopants and bubbles to the interfaces between the inner claddings, the outer cladding or tube, and the cores.

Abstract: The present disclosure relates to a fiber and a laser probe assembly with a probe tip that houses the fiber. In certain aspects, the fiber includes a core, an outer cladding surrounding the core, and an end face at a proximal and/or distal end of the fiber. The core is configured to transmit a laser light beam while the core and the outer cladding are both configured to transmit an illumination light. In certain aspects, a surface area of the end face corresponding to a cross-section of at least the outer cladding is treated with a roughening or polishing process to modulate an illumination light output angle of the fiber. Using a fiber that is configured to transmit a laser light beam as well as a wide-angle illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.

Abstract: The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

Abstract: Devices and methods are disclosed for an optical component mounting system for supporting an optical component such as a laser. The mounting system comprises a first component comprising a first surface, a second component comprising a second surface facing the first surface, and adhesive between the first surface of the first component and the second surface of the second component, wherein the first component comprises at least three mounting pads extending from the first surface for contacting the second surface of the second component and providing direct support between the first component and the second component. The component comprising the mounting pads may be a lower mount, an upper mount such as an upper clamping mount, or a bonding pad or other component in the stack of components. A method of assembling the stack of components may comprise curing the adhesive at a temperature at or above an upper end of an expected temperature operating range for the optical component mounting system.

Abstract: An ophthalmic illumination system can include an optical fiber configured to transmit a light beam output by a light source and focused by a condenser. The optical fiber can include proximal, distal, and central portions. The proximal portion can be configured to receive the light beam focused by the condenser. The distal portion can be configured to emit the light beam to illuminate a surgical field. The central portion can extend between the proximal and distal portions. A core diameter of the proximal portion can be larger than core diameters of the central and distal portions. An ophthalmic illumination method can include focusing, using a condenser, a light beam emitted by a light source onto a proximal portion of an optical fiber. The method can also include transmitting, using the optical fiber, the light beam to a surgical field.

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: In certain embodiments, an illuminating endoprobe system includes one or more light sources, a housing, a vitreous visualization fiber, and a general illumination fiber. The light sources generate a visualization light and an illumination light. The housing receives the visualization and illumination light, and has a probe tip with a probe axis. The vitreous visualization fiber transmits the visualization light through the probe tip. The visualization light has a visualization axis and a visualization beam angle at the probe tip. The general illumination fiber transmits the illumination light through the probe tip. The illumination light has an illumination axis and an illumination beam angle at the probe tip. The illumination beam angle is greater than the visualization beam angle, and the illumination axis is at an offset angle relative to the visualization axis, where the offset angle greater than 5 degrees.
