sub-Poissonian laser

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
Degree of coherence — In optics, correlation functions are used to characterize the statistical and coherence properties of an electromagnetic field. The degree of coherence is the normalized correlation of electric fields. In its simplest form, termed g(1), it is… … Wikipedia
Photon antibunching — generally refers to a light field with photons more equally spaced than a coherent laser field. More specifically, it can refer to sub Poisson photon statistics, that is a photon number distribution for which the variance is less than the mean. A … Wikipedia
Squeezed coherent state — In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value::Delta x Delta p =… … Wikipedia
Quantum optics — is a field of research in physics, dealing with the application of quantum mechanics to phenomena involving light and its interactions with matter. History of quantum optics Light is made up of particles called photons and hence inherently is… … Wikipedia
