  • Variable-spectrum high-power electrical pulse generator, and facility and equipment operating such a generator
    Patent number: 8716904
    Abstract: The present disclosure relates to a high-voltage pulse generator including a “frozen-wave” generation system for generating high-voltage pulses and a trigger system for triggering the pulses, the generation system including a first and a second photoconductor element, wherein the triggering system includes means for generating a laser light beam and means for splitting the laser beam into two laser beam fractions, each laser beam fraction being directed onto a photoconductor element of the generation system, the splitting means being capable of controlling the distribution of the respective powers of the two laser beam fractions as a function of the orientation of the polarization of the laser beam. The present disclosure also relates to a facility comprising multiple high-voltage pulse generators and electrooptic pump-probe equipment operating such a high-voltage pulse generator.
