Coherent Power Combining of Chirped-Seed Erbium-Doped Fiber Amplifiers

Abstract

Using a rapidly-chirped (5 × 10^(14) Hz/s) continuous-wave optoelectronic swept-frequency seed laser and two 3 W erbium-doped fiber amplifiers, we demonstrate simultaneous stimulated Brillouin scattering suppression, coherent power combining, and electronic beam steering, without imposing strict path-length matching requirements. Our platform presents a viable path toward high-power continuous-wave sources.
