DEVICE FOR CONTROLLING AMPLITUDE TRANSMISSION OF LIGHT BEAM

摘要

FIELD: physics.SUBSTANCE: device for controlling amplitude transmission of a light beam has a voltage source, a monoaxial electrooptic crystal in form of an x-section plate having on the upper surface linear control electrodes which are orthogonal to the z-axis of optical anisotropy of the electrooptic crystal, said electrodes being in form of an interdigital structure and forming a diffraction grating. The surface of the electrooptic crystal is coated with a first and a second polarising coating, the first polarising coating being applied on the lower surface of the electrooptic crystal such that its transmission axis makes an angle 0°
