Abstract
A laser device having a semiconductor body (1), which has a plurality of active layers (5, 9) arranged vertically one above the other and serving for generating laser radiation. The active layers are subdivided in the transverse direction into a plurality of emission zones (15) and are electrically connected in series in the vertical direction. The semiconductor body (1) is formed in monolithic integrated fashion, and a cooling element (2) is provided on which the semiconductor body (1) is arranged.
Claims15
A laser device comprising:
- a semiconductor body (1), which includes a plurality of active layers (5, 9) arranged vertically one above the other for generating laser radiation, each of said active layers being transversely subdivided into a plurality of emission zones (15), said active layers being electrically connected in series in the vertical direction, wherein said semiconductor body (1) is a monolithic integrated component;
- and
- a cooling element (2), on which the semiconductor body (1) is arranged.
