APPLICATION
The EOQ-BBO series Pockels cells are
transverse field devices. The low electrooptical coefficient of BBO results in high
operating voltages. The quarter-wave
voltage is proportional to the ratio of
electrode spacing and crystal length. As a
result, a smaller aperture device has lower
quarter-wave voltage. However, even for
3mm aperture devices quarter-wave
voltage is as high as 3.4KV@1064nm. A
double crystal design is available in order
to reduce required voltages and allowing
operation in half-wave mode with fast
switching times.

PRINCIPLE OF OPERATION
BBO is one of the electro-optic material
choices for high average power pockels
cell applications. BBO has significant
advantages over other materials in terms
of laser power handling abilities,
temperature stability, and substantial
freedom from piezoelectric ringing.
Because it relies on the electro optic
effect, switching time - aided by the low
capacitance of the Pockels cell is very
fast. The wide transparency range of BBO
allows it to be used in diverse applications.
