ABSTRACT:
A laser beam admitting device comprises a support structure for supporting an optical fiber having a core and a clad layer surrounding the core. Laser beam is admitted into a beam admitting end of the optical fiber through a condensing optical system. The support structure supports the optical fiber at a supporting location remote from the beam admitting end thereof. The support structure includes a tubular portion extending from the supporting location toward the beam admitting end of the optical fiber. The tubular portion has its inner diameter greater than an outer diameter of the clad layer of the optical fiber. A beam leakage material is disposed between the tubular portion and the clad layer, to allow the laser beam admitted into the clad layer to be diffused to the tubular portion.
