QUANTUM THEORY OF LASER OSCILLATION I,
Abstract
The foundations are laid for a quantum theory of laser oscillation based on the assumption that for a suitable choice of statistical ensembles the expectation values of the field vectors are non-vanishing in steady-state. Treating the macroscopic systems that supply energy to the active atoms and remove it from the field according to the dielectric approximation, all expectation values and correlation functions containing a field coordinate are related to expectation values and correlation functions referring to the atomic degrees of freedom alone. Equations of motion for the atomic currents, populations and two-time response functions are derived and solved in a semiclassical approximation. Amplitude fluctuations of the output field due to zero-point field fluctuations are calculated and shown to be finite and in agreement with experiment in several important respects.
