Abstract

We report what we believe to be the first experimental demonstration of coherent beam combining of two fiber amplifiers in a 100 ns pulse regime using a signal leak between the pulses. Pulses of 100 W stimulated- Brillouin-scattering limited peak power are combined with 95% efficiency, a residual phase error of λ / 27 , and no significant beam quality degradation.
