Abstract

We took a step forward on the basis of existing deduction, the formula of net gain coefficient of amplification of spontaneous emission of Er-doped fiber was given. Based on the data, which were provided by the reference, we calculated the net gain coefficients for different fiber length pumped at different pump power. Then theoretical curves were drawn. ASE spectra obtained experimentally were in excellent qualitative agreement with the ones obtained from theory. At last, the calculated optimal fiber lengths were given according to several common used wavelengths at the same pump power.
