Abstract
A system and a method for coupling multiple pump light beams to an active fiber. The system including an inverted conical disk, concave lens or glass wedge, an active fiber placed in a center of the inverted conical disk (or concave lens) or at a bottom facet of the glass wedge and a plurality of pump light sources. The system further includes a plurality of lenses for focusing pump light beams from pump light sources towards a side of the inverted conical disk, concave lens or glass wedge, wherein the inverted conical disk, concave lens or glass wedge, couples the pump light beams into the active fiber. A method for coupling multiple pump light beams to an active fiber. The method includes providing an inverted conical disk, concave lens or glass wedge. The method further includes providing an active fiber in approximately the center of the inverted conical disk (or concave lens) or at a bottom facet of the glass wedge. The method further includes pump light sources for emitting pump light beams and focusing lenses for focusing pump light beams toward the axis of the active fiber. Pump light beams are emitted towards the side of the inverted conical disk, concave lens, or glass wedge and coupled to the active fiber.
