(54) Title: MULTI-SPOT LASER SURGICAL PROBE USING FACETED OPTICAL ELEMENTS (57) Abstract: An optical surgical probe includes a handpiece, a light guide within the handpiece, and a multi-spot generator at a distal end of the handpiece. The handpiece is configured to optically couple to a light source. The light guide is configured to carry a light beam from the light source to a distal end of the handpiece. The multi-spot generator includes a faceted optical element with a faceted end surface spaced from a distal end of the light guide. The faceted end surface includes at least one facet oblique to a path of the light beam.
