What is a KDP crystal?
Potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (KD*P) crystals offer excellent UV transmission, damage threshold and birefringence. Deuterated KDP, or KD*P, features an extended transmission range in the infrared, IR-shifted OH absorption bands, and an increased electro-optic coefficient.
What is barium metaborate used for?
Barium metaborate is a microbiocide/microbiostat used as an industrial preservative in the manufacturing process of paints, paper/paper products, industrial adhesives and coatings. Barium metaborate products are formulated as soluble concentrates and ready-to-use solutions.
What is meant by nonlinear optics?
Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light.
What is a non linear crystal?
Nonlinear optical crystals are used in many different nonlinear parametric applications. To mention a few: second harmonic generation, difference-frequency generation, optical parametric amplification, and others. A proper crystal has to be chosen in order to use it for a particular application.
What is nonlinear optical crystals?
Nonlinear optical (NLO) crystals serves the goal for generating coherent laser in the ultraviolet (UV) and deep-ultraviolet (DUV) frequency range through second-harmonic generation (SHG). Noncentrosymmetricity is the criterion for the SHG to be allowed in the material.
How does a BBO crystal work?
BBO nonlinear crystal is a negative uniaxial crystal, which provides phase matching for various second-order interactions almost over its entire transparency range (from 185 nm to 3.3 µm, as deduced from the transmittance measurements using crystal samples of several mm thickness), making it a widely used crystal for …
Is barium a pesticide?
Barium metaborate was first registered in the United States in 1960 as broad spectrum bactericide and fungicide. Currently, four end use products (three of which are covered by this RED) and no technical or manufacturing use pesticide products are registered which contain barium metaborate as an active ingredient.
