Barium has been established as an alternate codopant other than conventional aluminum or phosphorous for fabrication of rare‐earth‐ (RE) doped optical fiber through modified chemical vapor deposition (MCVD) coupled with solution doping technique. Different optical and material characterization results of our fabricated fibers indicate potential application as amplifier and laser. The amplifier performance of Er‐doped fiber and lasing as well as photo darkening (PD) experiment of Yb‐doped fiber doped with BaO is presented where Ba serves as an alternate candidate for enhancement of RE solubility in silica glass.
