A coherent grating-surface-emitting diode-laser array has demonstrated dynamically stable operation in the 0 degrees phase mode. The array was operated under pulsed conditions, had a peak power output of 44 mW and a large central lobe on axis in the far field, and exhibited single-mode spectral output with better than 18-dB side-mode rejection.
