Abstract

An optical fiber amplifier or laser comprises an optical housing having a diffusive reflective inner surface and at least one opening for receiving pump light. An optical fiber having a doped core is at least partially contained within the optical housing. The optical fiber can be pumped by an optical source without the need for any complex or expensive optical couplers. Lateral illumination of the fiber core with pump light enables many fibers to be pumped by the same pump source, so that a separate dedicated coupler is no longer required to couple the pump light into each optical cable.
