Optically pumped semiconducting laser device has radiation emitting zone at first temperature, vertical emitter's radiation emitting zone at second, higher temperature when pump laser operating

摘要

The optically pumped semiconducting laser has a vertical emitter (2) and at least one pump laser (5) for optically pumping the vertical emitter, whereby the vertical emitter and pump laser are monolithically integrated. When the pump laser is operating, a radiation emitting zone (6) is at a first temperature and the vertical emitter has a radiation emitting zone (3) at a second, higher temperature.
