Abstract: An optoelectronic semiconductor component is provided that includes a primary light source and a secondary light source. The primary light source and the secondary light source are monolithically integrated in the semiconductor component so that only condensed matter is located between them. The primary light source includes a first resonator containing a semiconductor layer sequence which is electrically pumped during operation. A first resonator axis of the first resonator is oriented parallel to a growth direction (G) of the semiconductor layer sequence. The primary light source is configured to generate pump laser radiation (P). The secondary light source includes a pump medium for generating secondary radiation (S) and the pump medium is optically pumped by the pump laser radiation (P). The first resonator axis points past the pump medium.

Abstract: A light-emitting semiconductor component (99) comprising a laser bar (100) comprising at least two individual emitters (2), and a conversion element (300) arranged downstream of the laser bar (100) in the beam path, wherein at least some of the individual emitters (2) are arranged side by side in a lateral transverse direction (X), the laser bar (100) is formed with a nitride compound semiconductor material, the individual emitters (2) are configured to emit primary radiation (L1) during normal operation and the conversion element (300) is configured to convert at least part of the primary radiation (L1) into secondary radiation (L2), the secondary radiation (L2) having a longer wavelength than the primary radiation (L1).
