10 W peak-pulsed power emitted in a beam pattern 2×diffraction limit (DL) is obtained from a 40-element, 200 μm-aperture Al-free phase-locked antiguided array (λ=0.98 μm). 60% of the power resides in the central lobe, and the external differential quantum efficiency is 54%, for 1 mm-long optimised facet-coated devices
