Surface emitting semiconductor laser having an interference filter

摘要

A surface emitting semiconductor laser includes a semiconductor chip (1), which emits radiation (12) and contains a first resonator mirror (3). A second resonator mirror (6) is arranged outside the semiconductor chip (1). The first resonator mirror (3) and the second resonator mirror (6) form a laser resonator for the radiation (12) emitted by the semiconductor chip (1). The laser resonator contains an interference filter (9, 17), which is formed from an interference layer system comprising a plurality of dielectric layers.
