COHERENT BEAM Meaning and
Definition
-
A coherent beam is a term used in the field of optics to describe a focused, concentrated, and uniform beam of light that maintains its intensity and maintains a constant phase relationship between all of its individual waves or rays. In other words, it is a beam of light in which all the waves are in step with one another.
The coherence of the beam refers to the degree of correlation between the phases of the individual waves composing the beam. A highly coherent beam has waves that are all perfectly in phase, resulting in constructive interference and a strong and highly focused beam. On the other hand, a less coherent beam has waves that are out of phase, leading to destructive interference and a weaker or less focused beam.
Coherence is an important property of lasers, which are often designed to produce coherent beams. Lasers achieve this coherence by stimulating the emission of photons from excited atoms or molecules, resulting in a beam with a well-defined and stable phase relationship.
Applications of coherent beams include laser technology, where lasers are used in various fields such as telecommunications, medicine, manufacturing, and research. Coherent beams are also utilized in holography, interferometry, and in scientific experiments that require highly focused and uniform light sources.
Overall, a coherent beam is a concentrated and uniform beam of light that maintains a consistent and synchronized phase relationship between its individual waves or rays.

Etymology of COHERENT BEAM
The word "coherent" has its root in the Latin word "cohaerēre", which means "to stick together" or "to be connected". The term "coherent" was first used in the field of optics in the early 19th century, referring to the property of light waves that are perfectly phase-aligned, meaning that their crests and troughs are in perfect synchronization. A "beam" generally refers to a concentrated stream or bundle of light or particles. Therefore, the term "coherent beam" refers to a stream of light waves that are aligned and connected, maintaining a fixed phase relationship with each other.
