Non-linear crystal Cesium Lithium Borate (CsLiB₆O₁₀or CLBO) is well suited for UV applications and generates the 4th. and 5th. harmonics of the Nd:YAG fundamental laser wavelength. CLBO is transparent down to 190 nm and can be phase matched for type-II SHG to 640 nm and type-I to 477 nm. CLBO is more readily grown than BBO in that it melts congruently and it can be grown directly from the melt, which eliminates the scatter seen in BBO due to the flux inclusions. CLBO has excellent non-linear optical properties - larger angular and spectral bandwidths than BBO. It also has a lower deffthan BBO, but a smaller walk-off angle and high damage threshold: 26 GW/cm2, twice that of BBO. (33)

The material with the deepest known IR transmission, CsI is sometimes used for components in the widest range spectrophotometers. An extremely soft material it is extremely difficult to polish and so performance is compromised for range. Doped with thallium, CsI(Tl) is a useful scintillator that emits at a wavelength that is a good match for silicon photodiodes. Arrays of this material are used in security imaging systems. Being relatively soft, this material has found application in satellite-borne radiation detectors, which must withstand extreme shock and vibration along with rapid temperature changes. Cesium Iodide precipitated powders are used in solid phase pelletizing of samples for infrared spectroscopy. Advantages offered are: extended transmission range and low water absorption. Laser Use: CsI is used in the far infrared as a beamsplitter or as interferometer plates. Influence of Environment -- Moisture: Cesium Iodide is highly water soluble and polished faces of this material may be damaged by moisture in the atmosphere when the relative humidity is higher than 35%. Handling -- Orientation: Orientation must be done by x-ray techniques. Cleavage: Cesium Iodide does not cleave at room temperature. Cutting and Polishing: Cesium Iodide can be cut with a band saw. Standard polishing techniques can be used. (MT) (H)

Seeded vapor phase crystals are grown without contact with reactor walls, up to 40 mm diameter. Substrates for AII-BVIepitaxy and windows for special IR range.

CVD ZINC SELENIDE is chemically inert, non-hygroscopic, highly pure, theoretically dense and easily machined. It has extremely low bulk losses due to absorption and scatter, has a high resistance to thermal shock and is stable in virtually all environments. It is available in circular blanks and sheet material are available in stock to meet your most urgent delivery requirements. Custom diameters, rectangles, CNC-profiled blanks, generated lens blanks, prisms, and near-net shape domes can also be made to your specifications.
