Line-Width Reduction of a Laser Diode Array Using an External Cavity with Two Feedback Mirrors
-
Abstract
A novel Littman--Metcalf external cavity laser diode array with two feedback mirrors is introduced. The line-width broadening effect caused by smile can be reduced by the novel external cavity. At the drive current of 16A, the line-width is narrowed to 0.1nm from free-running width of 1.6nm with output efficiency of 84%.
