Microscopic Theory of Laser Master Equation up to the Fourth Order. II

Abstract

Based on the time-convolution-less formulation of the damping theory, time evolutions of the photon intensity and its fluctuation of a laser model with N identical two-level atom systems are investigated for various situations from a quantum-statistical mechanical point of view. The energy exchange effect between the photon field and atom systems on the time evolutions reveals to be well described by the formulation even the atom system is eliminated adiabatically.
