An optical device including an optical fiber having a longitudinal axis and an optical fiber core with a distal end having a distal terminating end configured to discharge a first laser energy in a first direction and a second laser energy in a second direction. The optical device also includes a fiber cap having an interior cavity and an opening to the interior cavity, where the distal end of the optical fiber core is received within the interior cavity through the opening. A cladding is included on the distal end of the optical fiber core between the optical fiber core and the fiber cap.

Surgical laser system and laser fiber

One described aspect is an optical fiber comprising: a fiber core that extends along a fiber axis, is configured to transmit a laser energy along the fiber axis, and terminates at a distal end; a first cladding that extends along the fiber axis, is adjacent to the fiber core, and terminates at a distal end; a coating that extends along the fiber axis and terminates at a distal end, wherein the coating is a gold coating; a second cladding that surrounds a portion of the gold coating along the fiber axis, and terminates at a distal end; an outer jacket that extends along the fiber axis and terminates at a distal end; and a fiber tip. Associated laser systems are also disclosed.
