A high-power and extremely high-gain hybrid fiber amplifier with the good noise figure (NF) performance is developed and investigated. It comprises a two-stage erbium-doped fiber amplifier as a pre-amplifier and an erbium/ytterbium co-doped double-cladding fiber amplifier as a post-amplifier. At the
