Abstract
A multi-mode pump laser having an output, and an optical fiber coupler. The optical fiber coupler has a first section and a second section. The first section of the optical fiber coupler comprises a multi-mode fiber which is optically coupled to the pump laser output. The second section of the fiber coupler comprises a plurality of single mode optical fibers each of which has an input which is optically coupled to the multi-mode fiber. The source further comprises a pump drive which is controllable to dither the optical center frequency of the light produced by the pump laser, so as to scramble modal power distribution at the inputs of the single mode optical fibers.
