M5000 High Voltage Linear Amplifier
Electro-op c modulators are voltage driven
devices and in general high voltages are required.
Pockels cells also almost always present a
capaci ve load to the driver which can cause
stability problems when used with amplifiers not
designed specifically for the purpose.
One of the most common applica ons for this
amplifier is to drive a longitudinal field KD*P
Pockels cell for analogue modula on. The Pockels
cell is then typically op cally biased to the quarter
wave opera ng condi on with a wave-plate so
that the cell is opera ng at its most linear point in
its transfer characteris c. The amplifier is then
able to apply a differen al voltage across the load
which swings by 2500V peak to peak and in
opposite phase on each of the terminals across
which the load is connected. This then produces a
field change in the device equal to that from a
5000V single ended amplifier which is sufficient for
full modula on with a single crystal KD*P cell such
as our EM500 range for wavelengths up to around
850nm. With a more sensi ve double crystal
Pockels cell, opera on is extended to over 1µm.

modulators
Full power –3dB bandwidth
of ~14kHz and small signal
bandwidth 100kHz.
Internal signal generator
Of course, with such high voltages present safety is
of paramount importance and the amplifier output
terminals are fi1ed with SHV safe high voltage BNC
type connectors (conven onal BNC are used on
the external input and monitor output).
