Abstract

We report on far field energy distribution control using a coherent beam combining femtosecond digital laser employing 61 tiled channels. Each channel is considered as an individual pixel where amplitude and phase are controlled independently. Applying a phase difference between neighboring fibers or neighboring fiber-lines gives high agility for a far field energy distribution and paves the way for deeper exploration of phase patterns as a tool to further improve the efficiency achievable with tiled-aperture/filled-aperture setups and far field shaping on demand.
