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 laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to 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: 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: 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.
