An optical surgical probe includes a cylindrical cannula; a light guide partially within the cannula to receive a light beam from a light source through a proximal end, to guide the light beam to a distal end of the light guide, and to emit the light beam through the distal end of the light guide; a multi-spot generator at a distal end of the cannula that includes an optical element with a proximal surface to receive the emitted light beam, and a focusing lens, positioned inside the optical element to focus the received light beam into a focused beam, wherein the optical element has a faceted distal surface to split the focused beam into multiple distally emitted beam-components when the optical surgical probe is operated in a fluid with an index of refraction of 1.30-1.40, and to confine the focused beam in the optical surgical probe when the optical surgical probe is operated in air. |

1. An optical surgical probe comprising:
a cylindrical cannula; a light guide partially within the cannula, configured
to receive a light beam from a light source through a proximal end,to guide the light beam to a distal end of the light guide, andto emit the light beam through the distal end of the light guide; a multi-spot generator at a distal end of the cannula, the multi-spot generator including
an optical element with a proximal surface to receive the emitted light beam, anda focusing lens, positioned inside the optical element to focus the received light beam into a focused beam, whereinthe optical element has a faceted distal surface, configured
to split the focused beam into multiple distally emitted beam-components when the optical surgical probe is operated in a fluid with a fluid index of refraction in the range of 1.30-1.40, andto confine the focused beam into the optical surgical probe when the optical surgical probe is operated in air. |
