Abstract: An electrooptical element is disclosed, made from a crystal, for an electrooptical modulator (EOM), for example, a Pockels cell, comprising a housing, with the crystal arranged therein in the form of a vertical cylinder, the both end surfaces of which form a front plane, for entry of a light beam and an outlet plane, at a separation from the above, with an annular electrode in contact with each of the above and with a retainer, between the housing and both the outer region of the crystal and the two annular electrodes. The invention is characterized in that the retainer is embodied as an O-ring, concentrically enclosing each annular electrode and forming a closed annular chamber between itself and the housing, made from an electrically-conducting material and a hardened sealing compound, filling the annular chamber.

Abstract: The invention relates to a pockels cell comprising two spaced-apart cubical RTP crystals that have a square cross section, are located one behind another, and are oriented towards each other so as to provide thermal compensation in the direction of radiation. Each of said RTP crystals is provided with electrodes on two opposite faces, said faces of one crystal being rotated by 90° relative to the faces of the other crystal and relative to the direction of radiation (5). Flexible, electrically insulating, high voltage-proof plastic mats which conduct heat well and rest against the inside of a cooling member are provided around the exterior faces of the electrodes.

Abstract: A Faraday rotator for a Faraday isolator with an input polarizer, with an output polarizer, with a roller-shaped optical crystal that is arranged therebetween and that is arranged symmetrical to its axis of symmetry, with a right hollow cylinder that surrounds this and has a hollow space made of a permanent magnetic material, which cylinder is axially magnetized and the magnetic field of which extends in the hollow space approximately parallel to the axis of symmetry that runs in only one direction from the north pole to the south pole, and with terminal magnets attached to each of the two end faces in the plane perpendicular to the y- and z-directions of the axis of symmetry, each of which is embodied as a hollow right cylinder and has a through-aperture in the extension of the axis of symmetry, is characterized in that each terminal magnet is largely radially magnetized with regard to the axis of symmetry at least by region, in that the one of the two terminal magnets is magnetized radially from interior to

Abstract: An electrooptical element is disclosed, made from a crystal (4), for an electrooptical modulator (EOM), for example, a Pockels cell, comprising a housing (5), with the crystal (4) arranged therein in the form of a vertical cylinder, the both end surfaces of which form a front plane, for entry of a light beam and an outlet plane (41), at a separation from the above, with an annular electrode (1) in contact with each of the above and with a retainer, between the housing (5) and both the outer region of the crystal (4) and the two annular electrodes (1). The invention is characterized in that the retainer is embodied as an O-ring (2), concentrically enclosing each annular electrode (1) and forming a closed annular chamber between itself and the housing (5), made from an electrically-conducting material and a hardened sealing compound (3), filling the annular chamber.

Abstract: During an initialization of a simulation of the behavior of an industrial plant containing a number of components, a particularly reliable parameter input is intended to be ensured with a particularly low outlay. To this end, in an initialization method provision is made, according to the invention, that for each component a component type is identified in each case and, in circuit terms, is characterized by a number of inputs and by a number of outputs for one parameter in each case. The initialization method uses a stored component-type-specific signal flow structure for the parameter of each output for specifying whether a parameter input is requested for a component.

Abstract: The invention relates to a transversal electrooptical modulator (10) which can be controlled by means of an electric amplifier, comprising at least two elements for modulating (11) the light wave of a laser beam, and can preferably be used for projection of TV images. The invention is characterized in that the modulator elements are arranged behind each other in relation to the laser beam, that a focusing device (14) is arranged both in front of and behind each modulator element, that an electric amplifier output (22, 23) is associated with each modulator element and that all electric amplifier (A) inputs (24, 25) are connected to the same control line (26) as the control signal.
