20 year experience servicing the most demanding laser applications with KD*P and KDP including large aperture Pockels cell (dia>20 mm) for high power laser system (e.g. ICF)
KDP, KD*P, KTP, RTP, BBO, and LN are grown by WISOPTIC in-house
Being purchased and trusted by dozens of laser companies worldwide
The EO Q-switch (Pockels cell) is an electro-optic device in which the crystal
produces linear changes in the birefringence of the crystal (in contrast
to the Kerr Effect, which is quadratic with E).
Pockels cells are essential components in various optical devices such
as Q-switches for lasers, free space electro-optical modulators, free
space switches.
WISOPTIC use highly deuterated DKDP (KD*P) crystal (D%>99%) to make high quality Q-switches with high laser induced damage threshold. These devices can rapidly and precisely control the laser output polarization direction as a function of applied voltage. Some of our Q-switches have wedged windows to ensure 0° offset and to minimize back reflections.
