Abstract
Tellurite fibers with 7500 ppm Er3+ concentration and diverse 2500–15,000 ppm Tm3+ concentrations were manufactured, and their amplified spontaneous emission (ASE) intensities 1550 nm band around were obtained for 980 and 790 nm pump laser. Maxima 187 nm bandwidth at −3 dB points using Er3+–Tm3+ co-doped tellurite optical fibers pumping at 790 nm was obtained, and energy transfer (ET) process between 4I13/2 Er3+ and 3F4 Tm3+ levels related with the amplifier quantum efficiency was studied from experimental and calculated lifetime.
