| Abstract: | This paper discusses the Characteristics of spontaneous emission in Erbium. dopedhber. Ittheoretically analyzes the nature of absorption cross section,spontaneous emission cross section,netgain coefficient and the relations of pump power、spontaneous emission power、fiber length、spontaneous emission spectra,respectively,in Erbium-doped fibers,A domestic Erbium-doped fiber isexperimentally tested;The absorption spectrum is measured with a white light source and amonochrometer,and,pumped with a l480nm-band laser diode,the spontaneous emission spectrum isexamined by an optical spectroscopy analyzer. |
