DKDP

DKDP crystal is widely applied for electro-optic application as Q-switch and Pockels cell. DKDP is routinely used for Q-switching applications from the uv up to about 1.1 µm where absorption limits its use in active cavities, although it can be useful at longer wavelengths when a few percent of absorption can be tolerated. KD*P has high optical uniformity and is useful for large aperture applications.
The device of longitudinal Pockels cell using crystal of >98% deuterated DKDP is normally used for Q-switch of laser radiation. These Pockels cells are manufactured from the crystals that have been specially selected for their low optical loss and strain free property. The crystal is in the form of a cylinder and two silver ring electrodes are used to produce the longitudinal electric field.
