Improvement of the emission characteristics of a multicore fiber laser using self reproduction in a multimode interference device (MMI)
Summary form only. The development of high power diode-pumped fiber lasers for cw or pulsed applications requires a good transfer of pump-to-fiber laser radiation, a high slope efficiency and management of thermal problems. For high power solitary femtosecond fiber lasers the chirp parameter should be small combined with a proper value of the group velocity dispersion. To have decided to use a multitude of doped monomode fibers (61) confined within a common pump core of large diameter (multicore fiber). We show that using a multimode interference device (MMI) being made up of a step index multimode fiber coupled to the multicore fiber the uncorrelated emission may be influenced via field reconstruction.
