Nonlinear dynamics of Raman lasers in the good and bad cavity limit

Research output: Chapter in Book/Report/Conference proceedingChapter


The origin of stabilities and chaos in Raman lasers [1] so far remains unexplained. In this report we give a clear physical and mathematical mechanism for such behaviour, the results of which are in excellent agreement with earlier experimental results. We establish a mathematical similarity between the equations describing a single mode Raman laser and those of the Haken/Lorenz model for a detuned two level laser. The physical mechanisms of lasing are, however, quite distinct since Raman emission involves a two-photon process between levels for which a population inversion is not required.
