COHERENT RADIATION Meaning and
Definition
-
Coherent radiation refers to a type of electromagnetic radiation in which the oscillation of electromagnetic waves is in perfect alignment with each other. It is characterized by its well-defined phase relationship between the waves and high degree of spatial and temporal coherence.
In contrast to incoherent radiation, which consists of waves that are randomly and independently generated, coherent radiation is produced when the sources of electromagnetic waves are synchronized. This synchronization results in a constructive interference, causing the waves to reinforce each other and create a single, intense, and focused beam.
Coherent radiation is commonly associated with laser light. In a laser, the light is generated by a process called stimulated emission, where photons are emitted in sync with other photons already present. Due to this synchronicity, laser beams exhibit the characteristics of coherence, including monochromaticity (a single wavelength) and directionality (a narrow beam).
The coherence of such radiation is vital for various applications, including spectroscopy, holography, telecommunications, and medicine. For instance, in holography, coherent radiation is used to create three-dimensional images by recording and reconstructing the interference pattern of coherent light waves. In medicine, coherent radiation is employed in laser surgery to precisely deliver energy to specific tissues or tumors.
Overall, coherent radiation stands out for its properties of phase alignment and high spatial and temporal coherence, making it an essential tool in numerous scientific, technological, and medical fields.

Etymology of COHERENT RADIATION
The word "coherent" comes from the Latin word "cohaerentem", which means "stick or cling together". It is derived from the Latin prefix "com-" meaning "together", and the verb "haerere" meaning "to stick or cling". The term "radiation" derives from the Latin word "radiare", which means "to emit rays or radiation". Therefore, the term "coherent radiation" refers to radiation that is emitted or transmitted in a manner where the waves are in phase and maintain a fixed relationship with each other.
