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

Using a rapidly-chirped (5\times 10^{14}~{\rm Hz}/{\rm 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 imp...

Description
Summary:Using a rapidly-chirped (5\times 10^{14}~{\rm Hz}/{\rm 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.
