The Pockels Cells (EO Q-Switches) from Artifex Engineering are compact, high quality units at OEM pricing.
These devices contain an electro-optic crystal using the Pockels effect. A voltage applied across the crystal generates birefringence, causing linearly polarized light propagating through the crystal to be resolved into two orthogonal vectors. The change in retardation between the two vectors (ellipticity) is proportional to the magnitude of the electrical field. A crossed polarizer analyzes the output beam, resulting in intensity modulation. Sub nanosecond response times can be realized.
