A huge KDP crystal grown at LLNL to be cut into slices and used on the National Ignition Facility.

Monopotassium phosphate (also potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate, MKP) -- KH₂PO₄ -- is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium, and is a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level. Aerial view of the lab and surrounding area. ...

Nonlinear optics use

As a crystal, it is noted for its non-linear optical properties. Used in optical modulators and for non-linear optics such as SHG (second harmonic generation). It has been suggested that crystallization processes be merged into this article or section. ... An optical modulator is a device in which a signal-controlled element is used to modulate a beam of light. ... Nonlinear optics is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization P responds nonlinearly to the electric field E of the light. ... Second Harmonic Generation (SHG) is a subcategory of nonlinear optics in physics. ...

Also to be noted is KD*P, Potassium DiDeuterium Phosphate, KD₂PO₄. Also used for similar applications with slighty different properties. Deuterium, also called heavy hydrogen, is a stable isotope of hydrogen with a natural abundance in the oceans of one atom in 6400 of hydrogen (see VSMOW; the abundance changes slightly from one kind of natural water to another). ...
