Active dielectric film laser

Abstract

A laser configuration of an optical amplifier that consists of an active dielectric thin film is described. Both the spatial and the temporal mode structure are studied. Analytical and numerical formulations are used to describe the effects of this laser configuration, and experiments are performed to verify the predicted results. It is predicted and observed that the resonator beam width is dominated by the active region width of the film, not by the resonator-mirror curvature.
