Abstract
An edge emitting semiconductor laser chip includes a semiconductor body, which comprises at least one active zone in which electromagnetic radiation is generated during the operation of the semiconductor laser chip. At least one contact strip is arranged on a top surface at a top side of the semiconductor body. At least two delimiting structures are for delimiting the current spreading between the contact strip and the active zone. The delimiting structures are arranged on both sides of the contact strip.
