2. Potassium dideuterium phosphate - Wikipedia

   en.wikipedia.org/wiki/Potassium_dideuterium...

   DKDP is monopotassium phosphate (KDP, or KH 2 PO 4), but using deuterium. Replacement of hydrogen by deuterium in DKDP lowers the frequency of O–H vibrations and their overtones (high-order harmonics). Absorption of light by those overtones is detrimental for the infrared lasers, which DKDP and KDP crystals are used for.

   Authors can upload documents in several formats for delivery via the KDP website and charge between $0.99 and $200.00 for their works. [1] KDP accepts books in 44 languages. [2] In 2016, Amazon also added a paperback option, and in 2021, a hardback (case laminated) option, both of which use print-on-demand technology.

4. Monopotassium phosphate - Wikipedia

   en.wikipedia.org/wiki/Monopotassium_phosphate

   Monopotassium phosphate can exist in several polymorphs.At room temperature it forms paraelectric crystals with tetragonal symmetry. Upon cooling to −150 °C (−238 °F) it transforms to a ferroelectric phase of orthorhombic symmetry, and the transition temperature shifts up to −50 °C (−58 °F) when hydrogen is replaced by deuterium.

5. Pockels effect - Wikipedia

   en.wikipedia.org/wiki/Pockels_effect

   Two or more crystal can be incorporated into a transverse Pockels cell. One reason is to reduce the voltage requirement by extending the overall length of the Pockels cell. Another reason is the fact that KDP is biaxial and possesses two electro-optic constants, r 63 for longitudinal configuration and r 41 for transverse configuration. A ...

6. Ice-type model - Wikipedia

   en.wikipedia.org/wiki/Ice-type_model

   For this model (called the KDP model), the most likely state (the least-energy state) has all horizontal arrows pointing in the same direction, and likewise for all vertical arrows. Such a state is a ferroelectric state, in which all hydrogen atoms have a preference for one fixed side of their bonds.

7. Potassium titanyl phosphate - Wikipedia

   en.wikipedia.org/wiki/Potassium_titanyl_phosphate

   Crystals of KTP are highly transparent for wavelengths between 350 and 2700 nm with a reduced transmission out to 4500 nm where the crystal is effectively opaque. Its second-harmonic generation (SHG) coefficient is about three times higher than KDP. It has a Mohs hardness of about 5. [3]
