If that happens the coherent wave will dissipate as heat - the atoms/molecules/electrons moving in random directions.

And valid for coherent forward-propagating waves in directions near the k-direction.

These methods involve the mixing (or superposition) of coherent light waves.

Maser is a device that produces coherent electromagnetic waves.

This phenomenon is typical of any coherent wave which is multiple scattered.

A maser is produces coherent electromagnetic waves through amplification due to stimulated emission.

Laser rangefinder, indirect by runtime measurement of coherent electromagnetic waves around the visible light region (lidar)

A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission.

We propose this is a coherent wave which puts together all that happens in the brain at that time.

Most systems use a low-powered "oscillator" laser to generate a coherent wave, and then amplify it.
