Place the pockels cell and pockels cell mount in the beam path. The beam should enter and exit at the center of the apertures. Connect the P1/P2 BNC cables to the pockels cell electrodes and corresponding amplifier outputs. While powered off, switch the amplifier command input settings to unipolar mode and 1kOhm input impedance.
Additionally you can use a 0.050 inch allen wrench to rotate the pockels exit cap to block the rejected portion of the beam. This removes the need to have an external safety beam dump or block.
Rotate the pockels cell for minimum transmission of the beam at the desired wavelength (910nm-960nm), while the bias voltage is set to 0V.
