What is a Beam of Light?PROF. GILBERT LEWIS'S views (NATURE, February 13, p. 236) stretch far, but will he, or any one else, begin at the first stage?doi:10.1038/117344c0P., FNatureNature
When discussing beam types, the continuous beam is essential to mention. Similar to a simply supported beam, it incorporates more than two supports. It has a hinged support at one end and a roller support at the other, with additional supports between them. Continuous beams find application in...

Beam spread can occur for two reasons, diffraction and diffusion. Diffraction occurs when the light beam is turned to a slightly different angle from passing through the lens. Diffusion is a gradual spreading of the light from dust, humidity and other particles in the air, which causes the ...

and a laser pump typically stimulates particles into a higher energy state. Each state is often referred to as a level; a three-level laser, for example, can direct light in three different stages before it is emitted. Such a configuration is often used to ensure that the beam is at the...
