10W near-diffraction-limited peak pulsed power from Al-free, 0.98 mu m-emitting phase-locked antiguided arrays

10 W peak-pulsed power emitted in a beam pattern 2xdiffraction limit (DL) is obtained from a 40-element, 200 mu m-aperture Al-free phase-locked antiguided array (lambda = 0.98 mu m). 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.
