Examples

  • The result is an essentially arbitrary-wavelength source of spatially coherent laser light.

    Academic text (2012)
  • Clearly it is a coherent signal.

  • So this is coherent light.

  • They were in phase when the coherent light struck these.

  • And as I said, this is the narrow beam of coherent light of very great intensity.

  • The laser is emitting coherent light, right?

  • The field of multidimensional coherent spectroscopy is still evolving, and new developments are occurring frequently.

    Academic text (2012)
  • Interferometry can be routinely performed with coherent radiation, which may be sound, electrons, x-rays, neutrons, or atoms.

    Academic text (2001)
  • Laser light is coherent because the waves maintain a consistent phase relationship.

  • For better results, we need to use coherent light sources in the experiment.

Morphology

coherent = cohere (semi-transparent) = cohere + ent

The physics sense ('constant phase relationship') is a specialized extension of 'togetherness' from 'cohere', so the morphological link is clear but domain knowledge is needed.

Etymology

Coherent comes from the Latin root haerēre 'to stick' with co- 'together', a bit like adhere. In physics a coherent wave keeps the same timing or 'sticks' in step with another wave, which is why they make clear patterns when they meet.
