Abstract

A highly efficient fiber-optic parametric amplifier (FOPA) is presented. A nearly complete pump depletion of 99.92% in a single-pumped FOPA is experimentally demonstrated with a pump power of $1\mathrm{W}$. In addition, a high signal output power of $0.53\mathrm{W}$ is presented, corresponding to a power conversion efficiency of 53%, which is believed to be the highest efficiency ever reported for an FOPA.
