An experimental study of visible fluorescence in erbium doped fiber pumped by laser diode at 806nm wavelength

While the erbium doped fiber is pumped by a laser diode operating at 806nm,the visible fluorescence at 460nm and 546nm wavelength are observed and measured. This paper give out the spectrum distribution curve of the fluorescence and the relation of the intensity of the visible fluorescence to pumping power.The system is compact and can be used as a low coherence light source of the fiber gyroscope or white light interferometer.
