High-power pulsed operation of 14.1W per uncoated facet from an optimized 3mm wide (510 {mu} m cavity length) nonplanar corrugated substrate periodic laser diode array is reported. Single-step metalorganic chemical vapor deposition growth over a selectively etched corrugated substrate provides suppressed lateral lasing and amplified spontaneous emission with a minimal number of processing steps. Higher external differential quantum efficiency, slope efficiency, and output power result from a design optimization with regard to the widths of the mesas and grooves of the corrugated substrate.
