A novel Littman-Metcalf exteal cavity laser diode array with two feedback mirrors is introduced. The linewidth broadening effect caused by smile can be reduced by the novel exteal cavity. At the drive current of 16 A, the line-width is narrowed to 0.1 nm from free-running width of 1.6nm with output efficiency of 84%.
