Patent ID: 8610990

Claim:
A driver for a Pockels cell having a first terminal and a second terminal, the driver comprising: a first circuit node connectable to the first terminal of the Pockels cell; a second circuit node connectable to the second terminal of the Pockels cell; a first voltage source at a first electric potential; a first switch connected to the first potential; a first wire conductor connecting the first circuit node to the first electric potential through first switch; a second voltage source at a second electric potential; a second switch connected to the second electric potential; a second wire conductor connecting the first circuit note to the second electric potential through the second switch; a third voltage source at a second electric potential; a third switch connected to the third potential; a third wire conductor connecting the second circuit node to the third electric potential through the third switch; a fourth voltage source at a fourth electric potential; a fourth switch; and a fourth conductor connecting the second node to the fourth electric potential through the fourth switch, wherein the first potential is more positive than the second potential, the third potential is more positive than the fourth potential, the difference of the first and fourth potentials is greater than the difference of the first and second potentials, and the difference of the first and fourth potentials is greater than the difference of the third and fourth potentials.
