Web2 de mar. de 2024 · The term "laser" is an acronym that stands for "Light Amplification by Stimulated Emission of Radiation". Laser light is a form of non-ionizing radiation. Laser equipment produces and amplifies light that has unique properties that cannot be produced any other way. The light that it produces is monochromatic - it is composed of one single ... Web1 de mai. de 2008 · A conventional laser comprises an optical gain medium, such as a gas, that is sandwiched between two mirrors in an optical cavity. The gain medium is “pumped” using an external source of light or electric field such that most of its atoms or molecules are in higher energy excited states. When these states decay, they emit light that bounces ... siamese twins fursona
