“…Furthermore, Hopf bifurcation to an oscillatory response is found to be most probable for self-defocusing, and to favour periods of order two round-trip-times . This is akin to the observations by Gibbs and coworkers [3] in an Na vapour cell with a feedback mirror, where such oscillations were observed mainly on the self-defocusing side of the atomic resonance .…”

“…To convey an understanding of how a lasing system with degenerate modes can be described in the SALT framework, let us first consider the well-known example of a rotationally symmetric ring laser whose solution can become unstable in certain parameter regimes [32,33,[40][41][42][43][44][45][46][47][48]. We model the system as a one-dimensional, homogeneous medium with periodic boundary conditions (see Fig.…”

“…This leaves only two possible steady-state lasing solutions of the ringlaser at¯, corresponding to the well known clockwise and counterclockwise traveling wave states. However, from the literature it is known that ring lasers show complex behavior, including the fact that these traveling wave solutions are not always stable [32,33,[40][41][42][43][44][45][46][47][48].…”

Steady-stateab initiolaser theory for fully or nearly degenerate cavity modes

We investigate the range of validity of the recently developed steady-state ab-initio laser theory (SALT). While very efficient in describing various microlasers, SALT is conventionally believed not to be applicable to lasers featuring fully or nearly degenerate pairs of resonator modes above the lasing threshold. Here we demonstrate how SALT can indeed be extended to describe such cases as well, with the effect that we significantly broaden the theory's scope. In particular, we show how to use SALT in conjunction with a linear stability analysis to obtain stable single-mode lasing solutions that involve a degenerate mode pair. Our flexible and efficient approach is tested on one-dimensional ring lasers as well as on two-dimensional microdisk lasers with broken symmetry.
