The MCVD and solution-doping technology for the Er-Yb co-doped double-clad fiber was reported.Using the MCVD manufacture technics,the fiber isolation layers(SiO2-P2O5-F) and the porous frits(SiO2-GeO2-P2O5) were deposited.The porous frits were soaked in the solutions of YbCl3 and ErCl3.Two fiber samples with 1:13 and 1:8 of Molar ratio Er/Yb were fabricated respectively.The maximium effective absorption coefficient of the sample 2 at the pump wavelengh 976 nm is 2 dB/m.The attenuation spectral and fluorescence characteristic were discussed.
