Abstract
The general formalism of an arbitrary ordering ofM-mode field operators is developed and this formalism is applied to a model of the superposition of coherent and chaoticM-mode fields having importance for a description of laser light. Corresponding probability distributions and their moments as well as their interrelationships are derived. Physically important relations for the normal, symmetric and antinormal orderings are deduced as special cases and a criterion of the existence of the weighting function of the Sudarshan-Glauber diagonal representation of the density matrix inL 2-space given.
