Coherent light are light waves that are "in phase" with one another. ... [ Two coherent waves ] ... Light produced by lasers are coherent light. Light from light bulbs or the sun, however, are incoherent light.

In physics, coherence is a property of waves, that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the electronic corr...

Ordinary light is not coherent because it comes from independent atoms which emit on time scales of about 10^-8 seconds. There is a degree of coherence in sources like the mercury green line and some other useful spectral sources, but their coherence does not approach that of a laser.

A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission . Laser light is usually spatially coherent, which means that the light either is emit...

This figure shows the emission of coherent light at 22 THz from a molecular dynamics simulation of shocked NaCl (table salt). The left panel shows the emission of the light as a function of time while the shock is propagating.

Where does "coherent light" fit into radio antennas, loudspeakers and water waves? And if my laser isn't coherent enough to make holograms, can I draw a picture of the exact nature of the problem? It just didn't connect.
