Any of several devices that produce very increased and coherent radiation of one or higher discrete frequencies. Probably one of the most typical lasers makes use of atoms in a metastable energy state that, while they decay to less energy level, stimulate other individuals to decay, causing a cascade of emitted radiation.
A device that produces a monochromatic, coherent laser beam.
A gum resin obtained from certain umbelliferous flowers.
Such a plant.
a computer device which creates an intense, frequently narrow, monochromatic beam of coherent light; known as additionally optical maser. It offers different forms, and is found in different applications in research and technology. The ray is created by boosting the majority of the electrons in certain radiation-absorbing atoms in a medium into an increased degree of energy, where these are generally stimulated by their emitted radiation to drop straight back synchronously to their reduced vitality, and give off light which is in phase (coherent).
A gum-resin obtained through the north of Africa, and greatly esteemed because of the ancients as an antispasmodic, deobstruent, and diuretic. It really is designed to were from Thapsia Garganica or one of the kinds of that plant. Also known as asadulcis.
An obsolete type of leisure.
an acronym for light amplification by stimulated emission of radiation; an optical device that creates a rigorous monochromatic beam of coherent light
