Abstract

Reconditioning a fiber for laser applications by cleaving off its tip and shaping the cleaved end into a conical or pyramidal shape with a grinder. The cleaved end is grasped in a fiber holder. The grinder is driven, e.g., to rotate. The fiber holder is moved relative to the grinder to bring it into contact with the moving grinder. The fiber holder may be rotated during the contact. Preferably, the axis of symmetry of the fiber is substantially parallel to the plane of rotation of the grinder to effect tangential grinding.
