We sketch the theory of a laser based on quantum dots which are pumped by a surface acoustic wave. Collective emission in the sense of superradiance is possible if the dots are identical and arranged along a straight line. In that case strong noise suppression is possible in the photocurrent spectrum, even for high output intensity.
