摘要：

Modulation multiplexing and beam cleanup are efficient techniques to coherently combine multiple fiber laser sources and achieve high power and very good beam quality. Using modulation multiplexing, three fiber amplifiers are coherently combined with a residual phase error of lambda/30. Using beam cleanup by stimulated Brillouin scattering in a multimode gradient-index fiber within a ring cavity, coherent combining of two fiber amplifiers with 50% efficiency and 99% slope is achieved. Further potential of these techniques is also discussed.
