Abstract
In an important 1979 paper,1 Petermann pointed out that, in certain laser resonator geometries, a typical mode may exhibit more noise than expected on the basis of the standard quantum mechanical "one photon per mode" prescription. It was subsequently shown by other authors2 that this arises because the self-producing field patterns that are commonly referred to as laser "modes" are not true modes of the radiation field. Rather than obeying the familiar condition of power-orthogonality, these satisfy the more general condition of biorthogonality with respect to a set of adjoint modes that correspond to the self-reproducing patterns travelling in the opposite direction.3
