Temporal Coherence

Main Question or Discussion Point

To spin my last post a bit further:

It appears that one could say then that the temporal coherence of a
given frequency spectrum can not be less than the coherence time
associated with the spectral width of any absorption features in the
spectrum.

temperature coherence or longitudinal coherence

assume the wave length has a uniform distribution from lamda to lamda+deltalamda

then after N period, N.*lamda=(N+1)*(lamda+deltalamda), N can be found, and N.*lamda is about the longitudinal coherence or temperal coherence.
As I read elsewhere, this concept is essentially a statistical consequence...
