Abstract

A fiber optic probe that eliminates extreme tip temperatures by radiating laser energy in a radial, 360° pattern from the surface of an exposed fiber optic tip is disclosed. In an embodiment, a fiber optic core is configured to operatively engage with a source of laser energy at a proximal end of the fiber optic tip, and, at a distal end of the fiber optic tip, includes a plurality of refracting surfaces configured to disperse laser energy in a radial pattern. In one embodiment, the refracting surfaces may be arranged as a plurality of annular prisms defined around the fiber core. In another embodiment, the refracting surfaces may be arranged as a plurality of concave lenses defined in the fiber optic tip. The temperature distribution of the disclosed probes is controlled and uniform, and may be tailored to radiate laser energy in any desired pattern which may be suitable to achieve an intended objective.
