Three types of quasi-stadium laser diodes, which have confocal, concentric, and geometrically unstable end mirrors, were fabricated by a reactive-ion-etching technique. It is shown that the experimental results on the lasing characteristics of these lasers excellently correspond to the theoretical results by the extended Fox-Li mode calculation method. The morphological effects on lasing modes are discussed from the viewpoint of raywave correspondence.
