Abstract : Recent experiments have revealed two distinct modes of operation of the internally modulated laser, the AM and FM modes, each of which removes almost all random phase and amplitude fluctuations in the laser output. A quantum theory of the modulation process is developed in terms of the travelling wave modes of an optical resonator. The theory predicts the effect of the modulator on an arbitrary wave packet of electromagnetic energy. A saturation analysis of the steady state operation of both the AM and the FM laser is performed in an effective linear response approximation. Effective gain curves are found and plotted for multimode AM, single mode AM and single mode FM cases. Experiments are suggested to test details of the modulation process whose effects are revealed by this analysis. (Author)
