26.6.78 1 PHN 8850 ABSTRACT "Semiconductor laser or intensifier". A semiconductor laser or traveling wave intensifier having an active layer between two passive semiconductor layers, and a strip-shaped electrode geometry. According to the invention the active layer is uniform in thickness, while at least one of the passive layers within the strip-shaped geometry comprises a strip-shaped zone of deviating construction and is built up from portions having different refractive indices n1 and n2. According to the invention it holds that (n1 - n2) (d1 - d2) > O, wherein n1 is the refractive index of the portion which at least within said strip-shaped zone adjoins the active layer, d1 is the thickness thereof within the strip-shaped zone, and d2 is the thickness thereof beside the strip-shaped zone.
