    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: The present disclosure generally relates to systems and methods for laser alignment, and more particularly, systems and methods for alignment of an optical element for laser transmission. In certain embodiments, a cover plate is configured to slide into place on an optic mounting plate. Positioning the cover plate applies force to a biasing element to press an optical element against a registration surface of the optic mounting plate to align the optical element with an optical aperture. The cover plate may be secured relative to the optic mounting plate to retain the biasing element and the optical element.

    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: Certain aspects of the present disclosure provide a probe comprising a tube, wherein one or more optical fibers extend at least partially through the tube for transmitting at least one of a laser light and an illumination light from a light source to a target location. A distal end of the tube comprises a flat-walled morphology, and a protective window with a round edge is press-fit to the distal end. The flat-walled morphology of the distal end of the tube has a reduced diametric interference sensitivity, thus allowing a wider range of tolerances between the window and the tube walls for effective press-fitting.
