In particular embodiments of the present invention, an optical surgical probe includes a handpiece configured to optically couple to a light source and a cannula at a distal end of the handpiece. The probe further includes at least one light guide within the handpiece. The light guide is configured to carry a light beam from the light source to a distal end of the handpiece. The probe also includes a multi-spot generator in the cannula that includes a faceted optical adhesive 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. In some embodiments, the probe also includes a high-conductivity ferrule at the distal end of the light guide. In other embodiments, the cannula is formed from a transparent material. |
