A laser diode pump includes a plurality of laser diodes each capable of generating
a lasing wavelength. The laser diode pump further includes at least one wavelength
combiner operable to combine the plurality of lasing wavelengths generated by the
plurality of laser diodes into a multiple wavelength pump signal. In one particular
embodiment, at least two of the plurality of lasing wavelengths generated by the
plurality of laser diodes comprise a wavelength between 1270 nm and 1350 nm.
