Coherent, Inc., headquartered in Santa Clara, California is an American company that develops, manufactures and supports laser equipment and related specialty components. Coherent was founded in May 1966 by physicist James Hobart and five cofounders.
Coherent was founded as II-VI Incorporated in 1971 by Carl Johnson and James Hawkey. [5] [6] The name "II-VI" is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride (cadmium belongs to group II and tellurium belongs to group VI).

Coherence (physics), an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference Coherence (units of measurement), a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one
To produce coherent light he passed the monochromatic light from an emission line of a mercury-vapor lamp through a pinhole spatial filter. In February 2011 it was reported that helium atoms, cooled to near absolute zero / Bose–Einstein condensate state, can be made to flow and behave as a coherent beam as occurs in a laser.
James Clerk Maxwell played a major role in developing the concept of a coherent CGS system and in extending the metric system to include electrical units.. A coherent system of units is a system of units of measurement used to express physical quantities that are defined in such a way that the equations relating the numerical values expressed in the units of the system have exactly the same ...
The Gaussian coherent states of nonrelativistic quantum mechanics can be generalized to relativistic coherent states of Klein-Gordon and Dirac particles. [38] [39] [40] Coherent states have also appeared in works on loop quantum gravity or for the construction of (semi)classical canonical quantum general relativity. [41] [42]
Coherent control is a quantum mechanics-based method for controlling dynamic processes by light. The basic principle is to control quantum interference phenomena, ...
A coherent space F over C is a family of C-subsets for which F = (F ⊥) ⊥. In Proofs and Types coherent spaces are called coherence spaces. A footnote explains that although in the French original they were espaces cohérents , the coherence space translation was used because spectral spaces are sometimes called coherent spaces.
