Product Details

E-O Q-switch based on DKDP (KD*P) crystals are one of the most popular Pockels cells in the market.

Deuterated potassium dihydrogen phosphate has good transmission from 390 nm to 1400 nm (0.39 μm – 1.4 μm) and combined with high electro-optical coefficients makes it suitable for Pockels cells.

Highly deuterated DKDP (D>99% – WISOPTIC) is necessary to reach effective electro-optical response. High laser induced damage threshold is guaranteed by applying special anti-reflective coatings on this hygroscopic crystal.

WISOPTIC standard DKDP Pockels cells are with longitudinal Electrooptic Modulation configuration.
