Article Description

The correlations of the fluctuations of the electric field are studied for a simple model of the buildup from spontaneous-emission noise of the output of a single mode of a laser cavity. Results for when the laser cavity is detuned with respect to the center frequency of the gain medium are compared with the case in which the cavity is resonantly tuned. Resonantly tuned lasers display transient phase and amplitude correlations with a peak at the time that the evolving amplitude departs from the neighborhood of the origin in the complex plane of the amplitude where phase diffusion dominates. Deterministic frequency chirps during the switch-on of a detuned laser delay and significantly strengthen the transient correlation of phase and intensity fluctuations when the detuning is sufficiently large compared with the strength of the noise. In this case the peak in the correlations is related to the anomalous intensity fluctuations characteristic of transient switching. © 1991 The American Physical Society.
