US 2006/0132900 A1 · Electrooptical element

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.
