Medical Definition of Coherent radiation
1.
Any form of radiation in which the phase relationship between sections of the wave at different locations is not random (or incoherent!).
Typical example is a laser beam, in which the phase is more or less uniform across the beam and changes along the beam in accordance with the wavelength. Radiation in which the photons tend to correlate with one another, rather than being randomly distributed.
