Collimated beam. In the lower picture, the light has been collimated. A collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates. A perfectly collimated light beam, with no divergence, would not disperse with distance.
In optics, a Gaussian beam is an idealized beam of electromagnetic radiation whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile.
The orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. It can be further split into an internal and an external OAM.
Light the Beam!" is a chant and rallying call in support of the National Basketball Association (NBA)'s Sacramento Kings. Referring to the Kings lighting a purple beam of light from their Golden 1 Center arena following a win, the phrase originated early during the Kings' 2022–23 season .
It is the speed of all massless particles such as photons, and associated fields —including electromagnetic radiation such as light —in a vacuum. It is predicted by the current theory to be the speed of gravity (that is, gravitational waves).

Jun 21, 2021 · The output beam from a typical gas laser, a He-Ne laser for example, exhibits the spatial variation ( 9.4.2 9.4.2) at the output mirror with w 0 approximately equal to 1 mm. Such a beam profile is called a Gaussian beam profile. The spatial Fourier integral in ( 9.4.1 9.4.1) can be inverted for z=0 to obtain.
