| 摘要 |
The invention relates to an optically pumped semiconductor laser apparatus having a vertical emitter ( 1 ) which has a central waveguide ( 3 ) and a quantum well structure which is arranged within the central waveguide ( 3 ) and has at least one quantum layer ( 5 ), and a pump radiation source, which optically pumps the quantum well structure and comprises at least one pump waveguide ( 9 ) in which the pump radiation ( 11 ) is guided. The width (A) of the central waveguide ( 3 ) is greater than the width (B) of the pump waveguide ( 9 ), with the width (A) of the central waveguide ( 3 ) and the width (B) of the pump waveguide ( 9 ) being matched to one another such that the quantum well structure of the vertical emitter ( 1 ) is pumped uniformly.
