Abstract: A diode laser comprises an n-type first cladding layer, an n-type first waveguide layer arranged on the first cladding layer, an active layer suitable for radiation generation and arranged on the first waveguide layer, a p-type second waveguide layer arranged on the active layer, a p-type second cladding layer which is arranged on the second waveguide layer, an n-type first intermediate layer being formed as a transition region between the first waveguide layer and the active layer, and a p-type second intermediate layer being formed as a transition region between the second waveguide layer and the active layer. The diode laser according to the invention is characterized in that the asymmetry ratio of the thickness of the first intermediate layer to the sum of the thickness of the first intermediate layer and the thickness of the second intermediate layer is less than or greater than 0.5.
