WebJan 6, 2024 · Coherent light is a form of light whose photons share the same frequency and whose wavelengths are in phase with one another. The light from a laser, such as a cashier's scanner, is a perfect example. The normalized first order correlation function is written as: where denotes a (statistical) ensemble average. For non-stationary states, such as pulses, the ensemble is made up of many pulses. When one deals with stationary states, where the statistical properties do not change with time, one can replace the ensemble average with a time average. If we restrict ourselve…
