Pockels Cells

A Pockels cell is a device containing an electro-optic crystal and using the Pockels effect. A voltage applied across the crystal generates birefringence, causing plane-polarized light propagating through the crystal to be resolved into two orthogonal vectors. The change in retardation between the two vectors is proportional to the magnitude of the electrical field. A crossed polarizer analyzes the output beam, resulting in intensity modulation.
