1. A side-firing laser fiber capable of emitting radiation, the laser fiber comprising:

  • a) a laser fiber through which laser radiation is directed, the laser fiber having an emitting tip;

    b) means for redirecting radiation at the emitting tip to a substantially side-firing angle from the longitudinal axis of the laser fiber; and

    c) a linear marking associated with said laser fiber, said linear marking extending a sufficient distance proximally from a position near the emitting tip so as to provide a reference with respect to the direction of radiation emitted from the emitting tip and to be visible even if the emitting tip is not itself visible during use, said linear marking being formed of a plurality of spaced-apart segments so as to permit measurement of the depth of insertion of the laser fiber into tissue and measurements within the surgical site.
