  • Circuit for controlling the thyratron in a pulse controlled metal vapor laser
    Patent number: 5243616
    Abstract: In order to avoid that the thyratron in a conventional laser pulse discharge circuit latches up in its conductive condition, a control circuit is introduced, which ensures that the thyratron is only triggered in intervals where the voltage across the primary coil L1 is decreasing or has reached an oscillation amplitude which is below a predetermined level.
