Popis: We present a very simple “toy model” that allows one to recover the essential mathematical and physical features that lead to excess quantum noise and excess linewidth in lasers with unstable resonators. In a consistent quantum mechanical description, the excess noise factor (Petermann factor) is physically attributed to loss-induced coupling between the cavity eigenmodes.
