Patent ID: 7023894

Claim:
An optically pumped semiconductor laser device having a substrate ( 12 ) having a first main area ( 14 ) and a second main area ( 16 ), a pump laser ( 30 ) and a vertically emitting laser ( 40 ) optically pumped by the pump laser ( 30 ) being arranged on the first main area ( 14 ), wherein the first main area ( 14 ) of the substrate ( 12 ) is patterned and has first regions ( 20 ) situated at a higher level and also second regions ( 18 ) situated at a lower level, the pump laser ( 30 ) is arranged on a region ( 20 ) situated at a higher level of the substrate ( 12 ), and the vertically emitting laser ( 40 ) is arranged above intermediate layers ( 50 , 30 ′) on a region ( 18 ) situated at a lower level of the substrate ( 12 ), the height difference (Δ) between the first ( 20 ) and second ( 18 ) regions of the substrate ( 12 ) and the layer thickness of the intermediate layers ( 50 , 30 ′) being chosen in such a way that the pump laser ( 30 ) and the vertically emitting laser ( 40 ) are situated at the same level.
