DKDP – Deuterated potassium dihydrogen phosphate

390 nm - 1400 nm

DKDP (KD2PO4) is an isomorphic single crystal (deuterated KDP). It can be grown using water-solution growing method with high level of deuteration (usually >98%)

DKDP crystals supplied by 3photon are used in non-linear optics systems, electro-optical (EO) applications especially with large apertures, they are also used in Pockel cells.

  • Applications
  • Features
  • Disadvantages

Nd:YAG, Nd:YLF laser systems: DKDP crystals are acting as laser frequency converters – for 2nd – 4th harmonic generation of low repetition rate (less than 100 Hz) and high pulse energy for Q-Switched and mode-locked lasers. It also could be used as a Q-switching crystal in these systems;

Ti:Sapphire and Alexandrite laser systems: as a Q-switching crystal;

Dye laser systems: for 2nd – 4th harmonic generation;

Electro-Optical applications: due to excellent electro-optic coefficients widely used as Electro-optical modulators, OPA/OPO;

Pockels cells: as Q-switching crystal, 3photon uses very highly deuterated (D2>98%) DKDP;

High speed photography: DKDP can be used as shutter.

  • Working wavelength 390-1400 nm;
  • Relatively easy growing technique ensures good price;
  • Can be grown very large in size;
  • Designed for specific wavelengths dielectric thin film anti-reflective coatings can be applied by 3photon;
  • Can be pumped using very wide range of pumping sources.
  • Hygroscopic (moisture effects DKDP instantly);
  • DKDP crystal material is soft, thus high-quality polishing is rarely achievable.
