DKDP – Pockels cells

0.39 μm - 1.4 μm

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.

• Features

   Our cells are crafted fro DKPD crystals with very high laser-induced damage thresholds (LIDT).

• DKDP crystals are securely protected by tight isolation, safeguarding both the crystal from environmental exposure and protecting laser electronics and personnel.
• 3photon engineers are capable of manufacturing cells in nearly any size, enabling faster and simpler installation compared to most market options.
• We utilize direct bonding of wires to the crystal, a departure from the common market approach of placing conductive connectors outside the crystal volume.
•  In place of protective windows, our coating engineers have applied anti-reflective (AR) coatings to shield the crystal and minimize light losses.

• Applications

DKDP Pockels cells are commonly used in Q-switching applications within the 390-1400 nm range.

3photon Pockels cells for laser cavity Q-switching are typically integrated into:

• Flashlamp-pumped Nd:YAG and Ruby lasers.
• Neodymium-doped DPSS lasers, including Nd:YLF, Nd:Glass, Nd:YAG, Nd:KGW.

In general, 3photon DKDP Pockels cells are versatile, serving applications in experimental R&D lasers, medical systems, industrial equipment, and even aerospace or military lasers:

• Ophthalmology laser systems;
• Q-Switching;
• Light intensity modulation;
• Cavity dumping;
• Quantum key distribution;
