Stripe geometry lasers grown by metalorganic-chemical vapor deposition lasing at 8260 A (approx.7% Al in the active region) are described. Pulsed current thresholds vary little with stripe width for 4-, 6-, and 8-..mu..m stripe widths. For 51 lasers that are 200 +- 10 ..mu..m long with 4-, 6-, or 8-..mu..m stripe widths, the average threshold currents were 40.4, 41.1, and 42 mA, respectively, and 37 of these lasers fall within +- 1 mA of these averages. External differential quantum efficiencies for these same lasers are 75, 67, and 63%.
