Abstract
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.
Claims20
A laser device comprising:
- a fiber extending along a fiber axis to a distal end of the fiber, wherein the fiber is configured to transmit laser energy along the fiber axis, the fiber comprising a core and a first cladding adjacent to the core;
- a second cladding surrounding at least a portion of the fiber;
- a metal coating between the first cladding and the second cladding;
- and
- a fiber tip;
- wherein a distal end of the first cladding is distal to a distal end of the second cladding and a distal end of the metal coating.
A laser device comprising:
- a fiber extending along a fiber axis, wherein the fiber comprises a core and a first cladding, the fiber being configured to transmit laser energy along the fiber axis;
- a coating over the fiber;
- a second cladding disposed over the coating and surrounding the fiber;
- a jacket at least partially surrounding the second cladding;
- and
- a fiber tip at a distalmost end of the laser device;
- wherein a distal end of the first cladding is distal to a distal end of the coating;
- and
- wherein the distal end of the coating is distal to a distal end of the second cladding.
A laser device comprising:
