An erbium/ytterbium co-doped double-cladding fiber amplifier with 36.4-dBm output power

We have described a high-power hybrid fiber amplifier, which comprising an erbium / ytterbium co-doped double-cladding fiber amplifier (EYCDFA) as a post-amplifier and a conventional erbium-doped fiber amplifier (EDFA) as a pre-amplifier. At the signal wavelength of 1550 nm, the signal gains of up to 71 dB and the maximum output powers of 36.4 dBm or 4.37 W have been demonstrated when the total pump laser power was 12.3 W.
