Abstract

Single frequency oscillation with a near diffraction-limited beam pattern is demonstrated from an otherwise multimode and multi-lobe high power GaAlAs laser array using a self-injection locking technique. A single mode output power of 500 mW with a single lobe far field beam of 0.5 deg divergence angle was obtained. The single frequency laser array also shows high frequency modulation response with high modulation depth and low distortion that make this laser array a suitable candidate for optical communication applications.
