Delivery system and method for surgical laser

A surgical laser delivery system for delivering laser radiation for performing surgery on a biological tissue, the system comprising:

• a laser having an output for emitting the laser radiation at a wavelength and a power level adapted for ablation of the biological tissue;
• a flexible waveguide having a first proximal end, a first distal end and a first length, the proximal end attached to the output of the laser;
• a rigid waveguide formed from a hollow metal tube having a polished interior surface, the rigid waveguide having a second proximal end connected to the first distal end of the flexible waveguide, a second distal end, a second length much less than the first length, and an interior cross-sectional area;
• a diamond tip having a base end with an entrance face, at least one sidewall, and a tip end with at least one exit face, the base end having an exterior cross-sectional area to closely fit within the interior cross-sectional area of the second distal end of the rigid waveguide so that the tip end extends from the rigid waveguide, the at least one sidewall having a surface for internal reflection of laser radiation within the diamond tip, wherein substantially all of the laser radiation is emitted through the at least one exit face and wherein the tip end is adapted for contacting the biological tissue for application of the laser radiation thereto.
