Phase synchronized modulatable resonant electro-optic modulator for switching high power laser pulses

摘要

The invention relates to an electrooptical modulator (1) for switching laser pulses (2) of a specific polarization and repetition frequency, comprising: at least one birefringent electrooptical crystal (3), a high voltage (4) applied at least temporarily to the electrooptical crystal (3) for varying the Polarization of the laser pulses (2), and at least one polarizer (5) for selecting laser pulses (2) of a specific polarization. The modulator (1) is characterized in that it comprises at least one excitable high-voltage resonant circuit (6) for generating the high voltage (4) as an alternating voltage, wherein the electro-optical crystal (3) in at least one switching state of the modulator as an electrical capacitance (7). the high-voltage resonant circuit (6) is formed, and the modulator (1) for changing its switching state comprises means (8) for manipulating the phase and / or amplitude of the AC voltage (4) applied to the electro-optical crystal (3).
