Abstract
In one embodiment of the invention, the semiconductor laser () comprises a semiconductor layer sequence (). The semiconductor layer sequence () contains an n-type region (), a p-type region () and an active zone () lying between the two. A laser beam is produced in a resonator path (). The resonator path () is aligned parallel to the active zone (). In addition, the semiconductor laser () contains an electrical p-contact () and an electrical n-contact () each of which is located on the associated region () of the semiconductor layer sequence () and is configured to input current directly into the associated region (). A p-contact surface () is electrically connected to the p-contact (), and an n-contact surface () is electrically connected to the n-contact () such that the p-contact surface () and the n-contact surface () are configured for external electrical and mechanical connection of the semiconductor laser (). The contact surfaces () are oriented parallel to a growth direction (G) of the semiconductor layer sequence (). The semiconductor laser () can be surface-mounted without wires.
