Unstable Behavior of Lasers and Other Optical Systems.

Abstract

This final report summarizes the theoretical and experimental activities carried out jointly by the Qauntum Optics Group at Drexel University and the Nonlinear Dynamics and Laser Physics Group at Bryn Mawr College during the period October 15, 1985 - August 31, 1987. The report includes detailed reviews of our major findings in the study of laser dynamics, especially theoretically, but also experimentally, and summaries of other parallel studies on Stimulated Raman Scattering (SRS) and nonlinear dynamics. Our emphasis has been on the formulation of a generalized version of the Maxwell-Bloch equations for the laser to include transverse degrees of freedom. We have succeeded in developing this model and have investigated in detail its steady state and linear stability properties. Our main result is the discovery of low threshold unstable behaviors and the identification of their physical origin. Keywords: Laser instabilities.
