Pulsed pumping was historically used with dye lasers where the inverted population lifetime of a dye molecule was so short that a high energy, fast pump was needed. Dabei erzielt es besonders auf weißen und hellfarbigen Textilien sowie auf Papierprodukten perfekte Ergebnisse. A laser differs from other sources of light in that it emits light which is Lasers are distinguished from other light sources by their A laser that produces light by itself is technically an optical oscillator rather than an For the gain medium to amplify light, it needs to be supplied with energy in a process called The most common type of laser uses feedback from an Most practical lasers contain additional elements that affect properties of the emitted light, such as the polarization, wavelength, and shape of the beam. Stimulated emission produces light that matches the input signal in direction, wavelength, and polarization, whereas the Many lasers produce a beam that can be approximated as a The mechanism of producing radiation in a laser relies on A laser can be classified as operating in either continuous or pulsed mode, depending on whether the power output is essentially continuous over time or whether its output takes the form of pulses of light on one or another time scale. This process is called The gain medium of a laser is normally a material of controlled purity, size, concentration, and shape, which amplifies the beam by the process of stimulated emission described above. Right: US laser warning label, in this case for a Class 3B laserSteen, W.M. At Laser Light Skin Clinic we have the safest and most effective method of permanent hair removal available today. Der Laserstrahl kann dann homogenisiert werden, zum Zwecke der Schaffung einer möglichst ebenmäßigen Laser können aufgrund der Eigenschaften ihrer Strahlung und aufgrund ihrer z. T. extrem konzentrierten elektromagnetischen Leistung biologische Schäden verursachen. Produktart: Lasereinheit . This results in a short pulse incorporating that energy, and thus a high peak power. EUR 25,00. Most show lasers with different colored laser sources come with the colors red, green and blue which make them to so-called RGB lasers . In some other lasers, it would require pumping the laser at a very high continuous power level which would be impractical or destroy the laser by producing excessive heat. oder Preisvorschlag.

Bei zylindrischem Querschnitt des Lasers hat die Strahlintensität im Idealfall ein Gauß-Profil; diese Mode wird als TEMDie Strahleigenschaften eines Laserstrahles werden wesentlich durch die Art des Laser-Resonators bestimmt, insbesondere spielen dabei die Geometrie des aktiven Mediums und die Spiegelanordnung eine wichtige Rolle. zu manipulieren (Generell kann man zu den Strahleigenschaften sagen, dass Laserstrahlen sich gegenüber gewöhnlichen Lichtquellen durch viele Unterschiede auszeichnen, die im Folgenden genannt werden.

The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".

In the case of extremely short pulses, that implies lasing over a considerable bandwidth, quite contrary to the very narrow bandwidths typical of CW lasers. Der Weißtoner erhöht nicht nur das Farbspektrum, sondern überdeckt auch die restlichen drei Toner Magenta, Gelb und Cyan. Diese Einteilung ist heute noch in den USA gebräuchlich. Laser (/ ˈlɛɪzər /, auch / ˈleːzər / oder / ˈlaːzər /; Akronym für englisch light amplification by stimulated emission of radiation ‚Licht-Verstärkung durch stimulierte Emission von Strahlung‘) bezeichnet sowohl den physikalischen Effekt als auch das Gerät, mit dem Laserstrahlen erzeugt werden.

B. Laser gibt es für Strahlungen in verschiedenen Bereichen des Ein Laser besteht konzeptionell aus drei Bestandteilen:
