WebA laser’s beam diameter characterizes the transverse extension of the beam, or its physical size perpendicular to the direction of propagation. It is often defined at the 1/e 2 width, which is bounded by the points where the beam’s intensity reaches 1/e 2 (≈ 13.5%) of its maximum value. WebA laser is a device that emits a beam of coherent light through an optical amplification process. There are many types of lasers including gas lasers, fiber lasers, solid state lasers, dye lasers, diode lasers and excimer lasers. All of these laser types share a basic set of components.
