Abstract
Summary form only given, as follows. Any conceivable configuration which involves the propagation of a laser beam in a (single-mode) fiber results in a mixing between the main beam and the Rayleigh scattering from the thermodynamically frozen inhomogeneities. This mixing converts phase fluctuations in the output of the laser to intensity fluctuations. The laser Langevin-oscillator equation for the phase statistics of the laser field has been solved, and the result has been applied to a statistical noise analysis of the scattering problem in the fiber. The result is a set of expressions for the total scattered power under a variety of experimental configurations and for the spectrum of the intensity fluctuations. The spectrum of the intensity fluctuations in a delayed homodyne system with arbitrary delays has also been obtained. The theoretical predictions and their practical implications are compared with experiments employing fiber lengths of up to 20 km and semiconductor lasers with different linewidths.
