Лазер – это источник монохроматичес

Лазер – это источник монохроматического когерентного света с малым расхождением светового луча светового пучка. Cлово «лазер» составлено из первых букв английского словосочетания, означающего «усиление света в результате вынужденного излучения». Действительно, основной физический процесс, лежащий в основе действия лазера, это вынужденное испускание излучения. Оно происходит при взаимодействии фотона с возбужденным атомом при точном совпадении энергии фотона с энергией возбуждения атома (или молекулы). В результате этого взаимодействия возбужденный атом переходит в невозбужденное состояние, а избыток энергии излучается в виде нового фотона с точно такой же энергией, направлением распространения и поляризацией, как и у первичного фотона.
В настоящее время созданы лазеры на самых различных средах – газах, жидкостях, стеклах, кристаллах. Лазеры нашли широкое применение в науке, промышленности, медицине. Так, например, были разработаны технологии сверления тонких отверстий (диаметром 1-10мкм и глубиной 10-100мкм) с помощью лазеров средней мощности. Основная область применения маломощных импульсных (pulsed) лазеров связана с резкой и сваркой (welding) миниатюрных деталей в микроэлектронике и электровакуумной промышленности.

Laser is the source of monochromatic coherent light with small beam divergence of the beam. Word "laser" is composed of the first letters of the English phrase meaning "light amplification by forced radiation". Indeed, the underlying physical process underlying the action of the laser, it is involuntary emission of radiation. It occurs when interacting with photon excited Atom with exact match the photon energy with the energy of excitation of the atom (or molecule). As a result of the interaction of the excited Atom moves in nevozbuždennoe State, and excess energy emitted in the form of a new photon with exactly the same energy, focus spread and polarization, as the primary photon. Currently, lasers are created on a wide variety of Wednesday-gases, liquids, glasses, crystals. Lasers are widely used in science, industry, medicine. For example, drilling technology have been developed thin apertures (diameter 1-10 μm and 10 deep-heat) using the medium-power lasers. The main field of application of the low-power pulsed (pulsed) laser is connected with sharp and welding (welding) of miniature details in microelectronics and electric-vacuum industry.

The laser - a source of monochromatic coherent light with a small divergence of the light beam of the light beam. The word "laser" is composed of the first letters of the English phrase meaning "light amplification due to stimulated emission." Indeed, the basic physical processes underlying the action of the laser, it is stimulated to emit radiation. It occurs when a photon interacting with an excited atom with exact coincidence of photon energy to the excitation energy (or molecules). As a result of this interaction, an excited atom enters the unexcited state and the excess energy is emitted in the form of a new photon with exactly the same energy, the direction of propagation and polarization, as well as at the primary photon.
Currently, lasers in on a variety of media - gases, liquids, glasses, crystals. Lasers are widely used in science, industry, medicine. For example, techniques have been developed drilling fine holes (diameter and depth 1-10mkm 10-100mkm) using a medium power lasers. The main field of application of low-power pulsed (pulsed) laser is associated with cutting and welding (welding) miniature components in microelectronics and electric vacuum industry.

the laser is a source of coherent light with a small difference монохроматического light ray of the light beam. replace "laser" is composed of the first letters of words, meaning "the world as a result of forced". indeed, the main physical process underlying the action of laser, the испускание radiation. it occurs in the interaction of photon with excited atom in the exact overlap energy photon with energy excitation of an atom (or molecule). as a result of the interaction of an atom is невозбужденное condition, and the excess energy is radiated in the form of a new photon with exactly the same energy, direction of incidence and polarization, and the primary photon.currently established lasers in various environments, gases, liquids, glazing, crystals. lasers have found widespread application in science, industry, and medicine. so, for example, developed the technology of drilling slim hole (diameter of 1 - 10мкм and depth of 10 100мкм) using high power lasers. the main scope of the application of low power laser pulse (pulsed) is associated with a sharp and welding (welding) of miniature parts in микроэлектронике and электровакуумной industry.
