    Abstract: A device for damping the vibrations of an elongated, substantially rectangular crystal in response to an applied high voltage electrical field comprises a pair of dielectric panes which are impedance matched with the crystal and are attached to opposite sides thereof. As attached to the crystal, each of the panes is disposed at the periphery of the electrical field, and an aluminum block is attached to each of the panes on a surface which is opposite from the crystal. The mass of aluminum blocks, and the texture of their exposed outer surfaces cooperate to mechanically dampen the acoustic vibrations transmitted from the crystal through the panes. Additionally, the rectangular dimensions of the crystal are chosen to delay the propagation of acoustic waves from the surfaces of the crystal to its center. This is done in order to preserve an optical window through the crystal for a period of time during which this window, at the center of the crystal, experiences only the electro-optical effect caused by an applied electrical field and does not experience the "ringing" which is caused by acoustic waves.

    Abstract: An electro-optic device, which processes by modulating, switching or gating, a light beam in response to an electrical signal utilizes an electro-optic crystal through which the beam to be processed passes. An electric field is generated by pulses which modulate the crystal's index of refraction and also causes piezoelectric ringing in the crystal. Acoustic energy absorbing material is coupled to the crystal for absorbing the piezoelectrically generated acoustic waves propagating perpendicularly to the applied electric field direction which has been found to be the dominant acoustic mode affecting the birefringence of the crystal and causing the ringing. The field is applied in short pulses (of the order of 10 nsec or less) thereby reducing lower frequencies in the acoustic energy spectrum thereby facilitating the absorption of the ringing energy. The modulation or gating of the optical beam may be carried out at high repetition rates which have heretofore limited the use of electro-optic devices to repetition rates of approximately 1 KHz or less.
