Dye laser — Close up of a table top dye laser based on Rhodamine 6G, emitting at 580 nm (yellow orange). The emitted laser beam is visible as faint yellow lines. The orange dye solution enters the laser from the left, and is pumped by a 514 nm (blue green)… … Wikipedia
Laser absorption spectrometry — (LAS) refers to techniques that utilize lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS).It is well known that optical spectroscopic techniques in general and laser based techniques in… … Wikipedia
Laser 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… … Wikipedia

Laser — A powerful beam of light that can produce intense heat when focused at close range. Lasers are used in medicine in microsurgery, cauterization, for diagnostic purposes, etc. For example, lasers are employed in microsurgery to cut tissue and… … Medical dictionary
Multiple-prism grating laser oscillator — Multiple prism grating laser oscillators,[1] or MPG laser oscillators, use multiple prism beam expansion to illuminate a diffraction grating mounted either in Littrow configuration or grazing incidence configuration. Originally, these narrow… … Wikipedia
Atomic vapor laser isotope separation — AVLIS Is an acronym which stands for atomic vapor laser isotope separation and is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions. In the largest technology… … Wikipedia
