A theoretical model for filled aperture coherent beam combining has been developed and the simulation results are validated through coherent beam combination of two 100 W laser beams using a diffractive optical element.

We have experimentally demonstrated 4 x 300 W coherent beam combining using filled aperture configuration and investigated the effect of polarization extinction ratio mismatch on the beam combining efficiency.

We report the comparison of beam combination efficiency and pointing error tolerance of Fermat spiral array with the conventional hexagonal geometry for coherent beam combining, which shows that the Fermat array exhibits better efficiency but tighter pointing error tolerance.
