Zusammenfassung:	To provide a light source, a light source device, and a light source driving method capable of simultaneously suppressing RIN and ripple, and a Raman amplifier and a Raman amplification system using the light source, the light source device, and the light source driving method. The light source includes a seed light source that outputs incoherent seed light with a predetermined bandwidth, and a booster amplifier as a semiconductor optical amplifier that optically amplifies the seed light input from a first facet, and outputs the amplified seed light as amplified light from a second facet. The first facet and the second facet of the booster amplifier are subjected to a reflection reduction treatment, the booster amplifier operates in a gain saturated state, and relative intensity noise (RIN) and ripple are simultaneously suppressed in the amplified light.
