Abstract:
1. An optical system, comprising: at least one elongate optical waveguide comprising an optical fiber having a first end, a second end, a lateral outer surface, an elongate laseable core disposed therein which is substantially parallel to a longitudinal axis of the elongate optical waveguide and a pump cladding disposed on and completely surrounding the laseable core; wherein a coating is disposed over the pump cladding; a source of lateral electromagnetic pumping energy disposed adjacent to the optical waveguide and having an emission axis that is directed toward the lateral outer surface of the optical waveguide; and an optically reflective surface disposed towards the lateral outer surface of the optical waveguide containing the laseable core to reflect substantially back toward the laseable core light which escapes the optical waveguide; wherein the reflective surface further comprises an optical dispersion surface that disperses laterally directed electromagnetic pumping energy that impinges on the dispersion surface into longitudinally directed modes.
