WebCoherent laser light has a much longer coherence time than incoherent lightbulb light. As the coherence time decreases, the phase evolves in time more rapidly (via phase jumps or otherwise), which means that the spectral linewidth of the light wave will increase, as we are deviating more strongly from a perfect single harmonic.

WebCoherent laser light is just pinhole-light produced by an infinite mirror-tunnel, with amplification. Sort of like those disco-era mirror-infinity toys from Spencer Gifts. But the depths of their virtual tunnel wouldn't be dark. … WebIncoherent light scattering. In the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects. Thus leaves appear green as chlorophyll pigments scatter green light, while it absorbs blue and red lights ...
