Abstract: An example laser probe comprises one or more fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the one or more fibers along at least a portion of the laser probe at or near the distal end of the laser probe. The laser probe further comprises one or more lens elements, where each lens element is fused to or formed directly on the distal end of a corresponding one of the one or more fibers. In some embodiments, the laser probe is a multi-fiber, multi-spot laser probe, e.g., comprising four or more fibers and four or more corresponding lens elements.

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.
