Surface emitting semiconductor laser for e.g. use in device for measuring speed and distance of object, has pumping laser provided for optical pumping of semiconductor laser to radiate pumping radiation in pumping pulses into chip

摘要

The semiconductor laser (1000) has a semiconductor chip (1), a resonator mirror (4) and another resonator mirror (8), which is arranged outside the semiconductor chip. The resonator mirror (4) forms a laser resonator with a resonator length (L), and a pumping laser (10) is provided for optical pumping of the semiconductor laser to radiate a pumping radiation (14) in individual pumping pulses into the semiconductor chip, where the resonator length is smaller than or equal to 10 millimeters. An independent claim is also included for a method for the production of a majority of surface-emitting semiconductor lasers.
