Stable in-phase coupled supermode operation of a ridge waveguide laser array is achieved by introducing distributed saturable absorption regions in subordinate laser cavities. Diffraction-limited single-lobed emission beams were attained up to 27 mW per laser stripe, and threshold current for the array was kept near 10 mA per laser stripe.
