Fabrication technology of erbium-doped glass samples is introduced. PhotoluminescencePLcharacterization of one sample or two samples in series are measured.The results show that the PL intensity of two samples is higher than that of one sample,and the full width at half maximum of two samples is approximately equal to that of a high concentration Er-doped sample.In the formation of two samples in series,the PL intensity with the high-concentration sample facing the pump laser source is higher than that with the low-concentration sample facing the pump laser source .The ratio of PL intensity of two low-concentration samples to PL intensity of a single sample is bigger than the ratio of PL intensity of two high-concentration samples to PL intensity of a single sample.
