A laser surgery system (10) includes a source of laser energy (14), a controller (13) operatively coupled to the source of laser energy (14), and a laser surgical instrument. The laser surgical instrument comprises: a cladding (22,42) having a first refractive index; a fiber optic core (21,41) coaxially disposed within the cladding (22,42) and having a second refractive index that is higher than the first refractive in-dex, the fiber optic core (21,41) configured to be operatively engage with the source of laser energy (14) at a proximal end; a fiber optic tip (27,47) formed on a distal end of the fiber optic core (21,41) wherein the fiber optic tip (27,47) extends outwardly from the cladding (22,42); and a plurality of refracting surfaces (25,45) formed around the fiber optic tip (27,47), each refracting surface (25,45) formed at least at one angle relative to a longitudinal axis (A) of the fiber optic tip (27,47) and configured to disperse the laser energy in a radial pattern. |
