In a more general background, a coherent state is just a state where coherences (off-diagonal terms in the density matrix) are non-zero, which means the state can skipp from one stationary state …
WebNov 13, 2024 · A rough way to describe how the word coherent is used in optics is to describe what kind of circumstances give rise to light not being regarded as 'coherent'. Let's say you are using a laser that is designed to automatically sweep out a spectrum. Let's say the spectrum takes seconds to be swept out.
