摘要：

An all-vapor phase modified chemical vapor deposition (MCVD) process has been proposed for the fabrication of active-fiber preforms with a fluorine-rich F-Yb2O3-GeO2-Al2O3-SiO2 glass core. The composition of the glass has been shown to differ significantly from that of the vapor-gas mixture because of the formation of GeF4, AlF3, and YbF3, which are volatile at typical MCVD temperatures. We have identified F-Yb2O3-GeO2-Al2O3-SiO2 glass deposition conditions that ensure uniform distributions of the dopants along the length of the preform.
