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 anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore … Ver mais Lasers are distinguished from other light sources by their coherence. Spatial (or transverse) coherence is typically expressed through the output being a narrow beam, which is diffraction-limited. Laser beams can be … Ver mais Electrons and how they interact with electromagnetic fields are important in our understanding of chemistry and physics. Stimulated emission In the Ver mais Foundations In 1917, Albert Einstein established the theoretical foundations for the laser and the Ver mais When lasers were invented in 1960, they were called "a solution looking for a problem". Since then, they have become ubiquitous, finding utility in thousands of highly varied … Ver mais A laser consists of a gain medium, a mechanism to energize it, and something to provide optical feedback. The gain medium is a material with properties that allow it to amplify light by way of stimulated emission. Light of a specific wavelength that passes through … Ver mais A laser can be classified as operating in either continuous or pulsed mode, depending on whether the power output is essentially … Ver mais Gas lasers Following the invention of the HeNe gas laser, many other gas discharges have been found to amplify light coherently. Gas lasers using many different gases have been built and used for many purposes. The Ver mais WebThe purpose of this standard is to provide guidance the safe use of lasers and laser systems found in research, development, or testing environments, where safety controls …
