Paper Abstract

Near-diffraction-limited CW operation at 1 W power level is demonstrated, for the first time, from all-monolithic phase-locked diode-laser arrays. In pulsed operation purely diffraction- limited beams (0.4 degree(s) lobewidth) are obtained from relatively large-aperture (120 micrometers ) devices to power levels of 1 W, with 70% of the energy in the central lobe at 0.1 W. These record-high coherent powers are obtained from 20-element resonant-optical-waveguide (ROW) arrays of antiguided diode lasers by significantly increasing the aperture width while maintaining strong discrimination against high-order array modes via Talbot-type spatial filters.
