Abstract
The present invention relates to a white light source. This white light source comprises a plurality of amplified spontaneous emission light generating sections each comprising at least an active fiber. At least two of the amplified spontaneous emission light generating sections are connected together in series. The plurality of amplified spontaneous emission light generating sections generate amplified spontaneous emission lights having at least partially overlapping wavelength ranges. Furthermore, a white light source of the present invention includes amplified spontaneous emission light generating sections each comprising at least an active fiber. At least one of the amplified spontaneous emission light generating sections comprises a mirror. If the white light source includes a plurality of amplified spontaneous emission light generating sections, at least two of the plurality of amplified spontaneous emission light generating sections are connected together in series to generate amplified spontaneous emission lights having at least partially overlapping wavelength ranges.
