Model 5056SC-A Q-switch Driver Modules integrate high voltage MOSFET circuits and self-contained miniature high voltage power supplies which require only +24 volts DC input. Trigger signals can be TTL level voltages. The 5056SC-A is intended for standalone operation with the company=s Series 1058, 1059, 1145, 1147 and 1150 electro-optic Q-switches operating at repetition rates between single-shot and 5 kHz repetition rates. It will also drive similar Pockels cells from other manufacturers. All circuits are packaged in an electrically shielded enclosure which attenuates EMI/RFI to minimize radiated and conducted switching noise. The 5056SC-A Output voltage is conveniently adjusted by a front panel mounted miniature potentiometer.
The 5056 features a balanced output, i.e., there are 2 independent output connections, one for each terminal on the Q-switch. The Switched and Unswitched HV outputs have identical HV DC levels which produce a static, zero net differential voltage across the crystal. When triggered, the Switched side goes to ground; the Unswitched side remains at HV resulting in a voltage pulse across the terminals.
Two other modes of operation are available without modifications. Referring to circuit diagram ; when a trigger signal is applied, Side 1 switches from the pre-adjusted HV level to ground and then, between laser pulses, is allowed to recover to its original value.
Side 2 always remains at the original HV level so that during the time Side 1 is at the ground level (ON time), pre-set retardation voltage is applied to the crystal. The Q-switched pulse is generated during the ON time. Given an appropriate Q-switch, the 5056SC-A permits operation at the 3 or 2 wave retardation voltages or at any voltage in this range. The 8 kV Model 5056SC-A-8 will produce pulsed voltages suitable for 3 and 2 wave retardation at 1064 nm with DKDP, BBO, RTP and Lithium Niobate Pockels cell Q-switches.

The 5056SC-A can also be operated as a SINGLE ENDED DRIVER "MODE 2" ; in this mode of operation, DC high voltage is applied to the Pockels cell (PC) to attain a static 3 or 2 wave retardation. The voltage may then be switched to the ground state. It will typically recover to the high voltage set point within ~150 μsecond time period. This operation is set up as follows: For "-A" series units with insulated wire leads, connect WHITE the lead from side 1 (PULSED) to a terminal on the Pockels cell. The other cell terminal should be connected to ground. The RED lead from side 2 (FIXED) is not used but it must be well covered and insulated with electrical tape since it is DC high voltage. The 5056 enclosure can be grounded by connecting the supplied wire lug to the 5056SC ground post. See product manual for details.
