Enhancement in pump inversion efficiency at 980 nm in Er(3+), Er(3+)/Eu(3+)+ and Er(3+)/Ce(3+) doped tellurite glass fibers

Amplification properties have been compared in Er(3+), Er(3+)/Eu(3+) and Er(3+)/Ce(3+) doped tellurite glass fibers using a 980 nm pumping scheme. The pump efficiency has been compared in the 3 types of fibers. Er(3+) ion upconversion in bulk glasses and fibers in visible range has been measured and...
