Paper Abstract

This communication describes the fabrication of Yb doped silica preforms by modified chemical vapor deposition (MCVD) method using Yb(C11H19O2)3 and AlCl3 in vapor phase. In order to investigate the optical quality of the preforms a systematic spectroscopic study was carefully carried out on various samples with different Yb and Al doping levels. In this way, the influence of the preforms composition on the Yb spectroscopic properties was studied in details, allowing the prediction of the composition favoring the laser emission with the highest efficiency. The predictions have then been validated after pulling the preforms in large mode area fibers (LMA).
