Laser technology

Laser technology is now an integral part of modern life. Thanks to their unique properties, lasers are used in manufacturing, medicine, the electronics industry and research and development. The technical demands made of optical components for lasers are extremely high, particularly regarding laser resistance and ray-forming specifications.

Components	Application	Materials
• Windows are optical components that only allow the passage of waves within a specific range. They come in a range of shapes and specifications (e.g. parallelism, surface quality, dimensional tolerances), depending on the type of application. • Prisms are optical elements that refract light or break it up into its constituent spectral colours by applying the principles of total internal reflection and wavelength dependant refraction. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, although not all prisms are this shape, depending on their application (e.g. pentaprism). • Lenses are optical components with two refractive faces, of which at least one is convex or concave. The most important property of a lens or array of lenses is its imaging properties. The most crucial aspect of a lens is its focal length, i.e. the measure of how strongly the system converges (focuses) or diverges (defocuses) light. The simplest lenses are spherical lenses: their two surfaces are parts of the surfaces of spheres, with the lens axis ideally perpendicular to both surfaces. Each of the surfaces can be convex (bulging outwards from the lens) or concave (depressed into the lens). As such, the surfaces can be assigned radii of curvature. A distinction is made between converging lenses (two convex faces or one convex and one planar face; ideally, a beam of light running parallel to the optical axis is collected in one point, the focus) or diverging lenses (two concave faces or one concave and one planar face; a beam of light after passing through the lens appears to be emanating from a particular point on the axis in front of the lens. used as laser windows • Laser protection windows • Beam shaper • Beam displacer • Beamsplitters Are optical devices that split a beam of light into two partial beams or beams of different wavelengths, where half the light is reflected and the other transmitted. This can be achieved with frustrated total internal reflection (using cube beam splitters), by using suitable dichroic optical coatings on dichroic mirrored prisms or by using Polka-Dot Structures. Special polarizing beam splitters (polarizing cubes) transmit or reflect light of differing polarization.	• VUV Excimer laser • Microlithography • CO2 Laser Cutter • White Light Generation • Barcode Scanner Mirrors	Calcium Fluoride Magnesium Fluoride Potassium Chloride Calcite Fused Silica YAG Zinc Selenide Zinc Sulfide
