Theory of line narrowing and frequency selection in an injection locked laser
Abstract
The multimode semiclassical laser theory is applied to the problem of line narrowing and frequency selection in an injection locked laser. The goal is to predict from the spectroscopic properties of a given active medium the behavior of a broad-band laser that is under the influence of a narrow-band injected signal. Analytic expressions for the injected signal strength necessary for single-mode operations are obtained for both homogeneously and inhomogeneously broadened lasers, and for small-signal and strong-signal regimes. It is found that under certain experimental conditions an injection locked inhomogeneously broadened laser behaves significantly different from a homogeneously broadened laser.
