laser radiation
41laser — n. [acronym from Light Amplification by Stimulated Emission of Radiation: ca. 1955.] A device which produces an intense, usually narrow, monochromatic beam of coherent light; called also {optical maser}. It has various forms, and is used in… …
42Laser engraving — is the practice of using lasers to engrave or mark an object. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean… …
43láser — m. instrum. Instrumento óptico que utiliza haces de luz en fase con el que se puede vaporizar o coagular pequeñas estructuras; se aplica en cirugía plástica, fotocoagulación de la retina, dermatología y destrucción de placas de ateroma, entre… …
44Laser propulsion — is a form of Beam powered propulsion where the energy source is a remote (usually ground based) laser system. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid… …
45Laser: Laserstrahlung und Aufbau eines Lasers — Auch wenn der Laser mittlerweile ein vielen Menschen vertrauter Begriff ist, sind doch wenigen die physikalischen Grundlagen seiner Funktion bekannt. Begriffe wie »Besetzungsinversion« oder »stimulierte Emission« werden bisweilen gebraucht,… …
46Láser de electrones libres — FELIX (Nieuwegein) El láser de electrones libres o FEL (acrónimo de free electron laser en inglés) es un láser que comparte las propiedades ópticas de láseres convencionales, es decir, la emisión de un haz coherente de radiación electromagnética… …
47Laser pumping — is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When the number of particles in one excited state exceeds the number of particles… …
48Laser bonding — is a marking technique that uses lasers and other forms of radiant energy to bond an additive marking substance to a wide range of substrates. Invented in 1997, this patent protected technology[1] delivers permanent marks on metals, glass and… …
49Laser cooling — refers to the number of techniques in which atomic and molecular samples are cooled through the interaction with one or more laser light fields. The first example of laser cooling, and also still the most common method of laser cooling (so much… …
50Laser: Die Grundlagen — Anders als natürliche und konventionelle Lichtquellen (z. B. Sonne, Glühlampe) ist Laserlicht sehr intensiv, einfarbig und scharf gebündelt. Jede einzelne dieser Eigenschaften zeichnet den Laser aus und erschließt ihm dadurch neue… …
