The generation of gravitational radiation by coherent excitation of a long row of oscillators is investigated. In particular diatomic linear chains are considered as an idealization of thin piezoelectric crystals. A highly focussed superradiant beam of gravitational radiation in the direction of the row and a total radiation power larger than the incoherent superposition of the oscillator radiation are found. In spite of these optimum conditions it seems that the attainable magnitude of the radiation power of approximately 10 to the -22nd erg/sec is not high enough for a successful laboratory experiment.
