dielectric crystal laser
1Laser diode — Top: a packaged laser diode shown with a penny for scale. Bottom: the laser diode chip is removed from the above package and placed on the eye of a needle for scale …
2Laser pointer — A laser pointer is a portable, pen sized laser designed to be held in the hand, and most commonly used to project a point of light to highlight items of interest during a presentation. Most laser pointers have low enough power that the projected… …
3Crystal oscillator — A miniature 4 MHz quartz crystal enclosed in a hermetically sealed HC 49/US package, used as the resonator in a crystal oscillator. A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal …
4Crystal structure — In mineralogy and crystallography, crystal structure is a unique arrangement of atoms or molecules in a crystalline liquid or solid. A crystal structure is composed of a pattern, a set of atoms arranged in a particular way, and a lattice… …
5Crystal — Crystals redirects here. For other uses, see Crystals (disambiguation). This article is about crystalline solids. For the type of glass, see lead crystal. For other uses, see Crystal (disambiguation). Quartz crystal. The individual grains of this …
6Photonic crystal — The opal in this bracelet contains a natural periodic microstructure responsible for its iridescent color. It is essentially a natural photonic crystal, although it does not have a complete photonic band gap. Photonic crystals are periodic… …
7Liquid crystal — Schlieren texture of liquid crystal nematic phase Liquid crystals (LCs) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal.[1] For instance, an LC may flow like a liquid, but its… …
8Liquid crystal display — LCD redirects here. For other uses, see LCD (disambiguation). Reflective twisted nematic liquid crystal display. Polarizing filter film with a vertical axis to polarize light as it enters. Glass substrate with ITO electrodes. The shapes of these… …
9Quantum cascade laser — Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid to far infrared portion of the electromagnetic spectrum and were first demonstrated by Jerome Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson,… …
10Liquid crystal on silicon — Conceptual diagram of the LCoS technology. Liquid crystal on silicon (LCoS or LCOS) is a micro projection or micro display technology typically applied in projection televisions. It is a reflective technology similar to DLP projectors; however,… …
