A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation..The word "laser" is an acronym [1] [2] for "light amplification by stimulated emission of radiation"..[3] [4] [5] The first laser was built in 1960 by Theodore H.. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and ..
Laser phosphor projection offers many benefits: Saves time and money – solid state illumination eliminates the need to replace lamps and filters, reduces consumables and waste, effectively lowers maintenance by reducing downtime, therefore lowering your total cost of ownership.. Long operational life – 20,000 hours to 50% brightness..
Energy storage On photostimulable phosphor (PSP) plates, the phosphor layer is typically 0..1 to 0..3 mm thick.. After the initial exposure by short-wavelength (typically, X-ray) electromagnetic radiation, excited electrons in the phosphor material remain 'trapped' in 'colour centres' ("F-centers") in the crystal lattice until stimulated by the second illumination..
Laser excited phosphor (LEP) is the process of emitting a blue laser through a focused lens onto a phosphor element backed by a metal substrate.. The laser is then reflected (bounced) off the phosphor and converted to broad-spectrum light.. In a flashlight, the resulting white light is directed out the end via a series of lenses..

Phosphor wurde 1669 von Hennig Brand, einem deutschen Apotheker und Alchemisten, entdeckt, als er – auf der Suche nach dem „Stein der Weisen“ – Urin bis zur Trocknung eindampfte.. Als Brand den trockenen Urin-Rückstand, der – wie heute bekannt – auch Phosphate (Salze der Phosphorsäure) enthält, unter Luftabschluss – also in Abwesenheit eines Oxidationsmittels – glühte ..
Excimer laser.. An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining.. Since 1960s excimer lasers are widely used in high-resolution ..
A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy..The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow when struck by an electron beam (cathode rays) in a cathode-ray tube..
