Description

Demonstration of a polarisation maintaining all-fibre coherent beam combining system, digitally implemented using a FPGA and electro-optic modulators. The experimental implementation combines three 7 W Erbium-doped polarisation maintaining fibre amplifiers with greater than 95% efficiency and $\lambda/493$ RMS phase stability.
