Laser device including optical pump extended cavity laser

摘要

The present invention describes a laser device capable of controlled emission of individual laser beams. The laser device includes an optical pump extended cavity laser with one gain element, whereby a number of pump lasers are provided. In order to generate an independent pump beam and hence a corresponding laser beam. Laser devices may be used to allow simplified or improved laser systems. For example, it is like a two or three dimensional laser printer. The pump laser may be a VCSEL and the laser may be a VECSEL monolithically integrated with the pump VCSEL array on the same substrate. The pump mirror and the external cavity mirror may be integrated into one light reflector with regions with different curvatures. Laser emission is controlled by pumping light. That is, the transverse shape of the laser beam and / or the number of laser beams are controlled by switching on / off of individual pump lasers.
