Light in which the phases of all electromagnetic waves at each point on a line normal to the direction of the the beam are identical. Coherent light is usually monochromatic, and the most common source of such light for practical uses is from a laser.
Illumination in which phasor amplitudes at all object points vary in unison, such as light from a point source or a laser.
Light in which all parameters are predictable and correlated at any point in time or space, particularly over an area in a lane perpendicular to the direction of propagation or over time at a particular point in space.
Theoretically, light in which the waves are all of the same length and in unchanging relationship to each other, as approximated by a laser beam (Zelanski).
Is light in which all the wavelengths are in alignment (ie. all the crests are alignment and all the troughs aligned).
Light made up of photons that have the same wavelength and are all in phase and thereby very energy efficient. An example is a laser.
A beam of light composed of wavefronts that are vibrating in the same phase, although not necessarily lying in the same plane of vibration. To maintain a common phase over long distances, coherent wavefronts must be monochromatic (have the same wavelength). As an example, most laser sources produce monochromatic, linearly polarized, highly coherent wavefronts.
Radiant electromagnetic energy of approximately the same wavelength with fixed phase relationships between different points in the field.
Light which is of the same frequency and is vibrating in phase. The laser produces coherent light.
Light or radiation composed of wave trains vibrating in phase with each other. Parallel rays of light.
Light that stays focused, a property of lasers.
coherence refers to the state or property of being together. Coherent light may be broken down into temporal coherence and spatial coherence.
light waves that vibrate with constant phase relationships. They can be produced by a laser or a combination of two prisms.
Light such that all of the associated waves have the same wavelength and are in phase.
