WebPhase noise measurements are often based on a recorded beat note between two lasers on a fast photodiode. (This requires that the difference of the optical frequencies is not too large.) Alternatively, it is possible to record a beat note of the laser output with a different portion of the same laser output, which is subject to a long delay, e.g. by propagation …
