ABSTRACT:
An apparatus for pumping an optical gain medium, such as a fiber gain medium, comprises a pump source having a plurality of different spatially separate or multiple wavelengths or wavelength bands which are all coupled into the fiber gain medium and provide at least one or more wavelengths to fall within the absorption band of fiber gain medium producing gain despite wavelength shifts in the pump source multiple wavelengths due to changes in the operating temperature of the pump source. At least one or more of the pump wavelengths will overlap the gain spectrum of the fiber gain medium sufficiently to continually provide high input power for pumping of the fiber gain medium.
