Abstract: Acousto-optic resonances in a crystal of a material exhibiting the linear electro-optic effect may be suppressed by coupling to the respective lateral faces of the crystal a plurality of slabs of a material having high acoustic energy absorption properties and an acoustic impedance substantially matching the acoustic impedance of the crystal. Lead, lead glass or titanium are exemplary appropriate acoustic energy absorbing materials for gallium arsenide or cadmium telluride crystals. A layer of either a non-bonding acoustic energy coupling material (such as silicone grease or indium), or a coupling and bonding material (such as shellac) is disposed between each absorbing slab and the adjacent crystal face.
