Divergence (disambiguation) — Divergence can refer to: In mathematics: Divergence, a function that associates a scalar with every point of a vector field Divergence (computer science), a computation which does not terminate (or terminates in an exceptional state) Divergence… … Wikipedia
Beam parameter product — In laser science, the beam parameter product (BPP) is the product of a laser beam s divergence angle (half angle) and the radius of the beam at its narrowest point (the beam waist).cite web|url=http://www.rp photonics.com/beam parameter… … Wikipedia

Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… … Wikipedia
Gaussian beam — In optics, a Gaussian beam is a beam of electromagnetic radiation whose transverse electric field and intensity (irradiance) distributions are well approximated by Gaussian functions. Many lasers emit beams that approximate a Gaussian profile, in … Wikipedia
Collimated light — In the lower picture, the light has been collimated. Collimated light is light whose rays are parallel, and therefore will spread slowly as it propagates. The word is related to collinear and implies light that does not disperse with distance… … Wikipedia
RFQ Beam Coolers — RFQ stands for Radio Frequency Quadrupole (also known as a Quadrupole mass analyzer when used as a mass filter), an instrument that is used in mass spectrometry. The RFQ was invented by Prof. Wolfgang Paul in the late 50 s / early 60 s at the… … Wikipedia
