  • Pockels cell driver circuit comprising resistive, inductive or capacitive elements
    Patent number: 9846319
    Abstract: The driver circuit comprises a first node (J1), which is connected to a first terminal of the Pockels cell (CP), a second node (J2), which is connected to a second terminal of the Pockels cell (CP), wherein the first node (J1) is connected to a first potential (+HV) via a first switching unit (S1) and the second node (J2) is connected to the first potential (+HV) via a second switching unit (S2) and wherein the first node (J1) is connected to a second potential (?HV) via a first resistance (R1) and the second node (J2) is connected to the second potential (?HV) via a second resistance (R2); and wherein the first node (J1) is connected to the second node (J2) via a series circuit comprising a third resistance (R3) and an inductance (L1).
