Pockels cells utilizing DKDP crystals are among the most popular choices on the market.
Deuterated potassium dihydrogen phosphate (DKDP) provides excellent transmission from 390 nm to 1400 nm (0.39 μm – 1.4 μm), and its high electro-optical coefficients make it ideal for Pockels cell applications.
To achieve an effective electro-optical response, highly deuterated DKDP (D > 97% – 98%) is essential. The high laser-induced damage threshold is ensured by applying specialized anti-reflective coatings on this hygroscopic crystal.
The 3photon standard DKDP Pockels cells feature a longitudinal electro-optic modulation configuration.
With no enter-exit windows, 3photon Pockels cells minimize light losses. These cells are lightweight, well-protected with durable anti-reflection coatings, and designed for easy installation.
