Abstract
A laser diode having a semiconductor layer sequence based on a nitride compound semiconductor material includes an n-type cladding layer, a first waveguide layer, a second waveguide layer and an active layer, and a p-type cladding layer including a first partial layer and a second partial layer, wherein the first partial layer includes AlGaN with 0≤x1≤1 or AlInGaN with 0≤x1≤1, 0≤y1<1 and x1+y1≤1, the aluminum content x1 decreases in a direction pointing away from the active layer so that the aluminum content has a maximum value x1and a minimum value x1<x1, and the second partial layer includes AlGaN with 0≤x2≤x1or AlInGaN with 0≤x2≤x1, 0≤y2<1 and x2+y2≤1.
