ABSTRACT:
A Pockels cell driver using a microwave triode which transfers charge from a high voltage source to a Pockels cell via a storage capacitor. The microwave tube is controlled, through its grid voltage, by two pulse amplifiers each having a plurality of tandem field effect transistor (FET) stages so as to increase the voltage across the cell in two steps having a selected delay therebetween. The driver is especially useful for seeding and extracting output pulses from a regenerative laser amplifier having the Pockels cell within its cavity. The driver may be used to operate a Pockels cell as a switchout or shutter to select a single pulse from a pulse laser such as a mode-locked Q-switched laser.
