Abstract
An electro-optical light modulator having a reduced piezo-optical effect by providing a plurality of optically series-connected modulator crystals having geometric dimension differing from one another such that for pulse control the overlapping of acoustical transients generated in the individual modulator crystals is excluded, along the beam path and where periodical control is used, the overlapping of the piezo-electrical resonant frequencies of the individual modulator crystal is excluded.
