Paper Abstract

The stripe area of a semiconductor laser with a diverging lenslike medium and a rectangular current-injection stripe is limited by efficiency considerations and by design constraints required to provide a coherent output beam. A larger stripe area is practical in a compound resonator with a lenslike medium in one portion and free expansion of the mode in the other portion. The stripe edges along the direction of propagation should match light rays of the mode on the output pass, at least approximately. Equations for the geometric properties of such a laser are derived, and a numerical simulation indicates that output power in excess of 4 W should be practical impulsed operation. The code did not include thermal effects, so CW operation is not simulated.
