PHASE MODEL ANALYSIS OF 2 LASERS WITH INJECTED FIELD

We study the dynamics of two coupled solid state lasers subject to an injected field. A singular perturbation technique is used to reduce th e full set of rate equations; we present a comprehensive bifurcation a nalysis of the resulting phase model. We find four distinct routes to full entrainment as the injected field amplitude increases; bifurcatio n diagram predicts that the entrainment (reflected in the total intens ity) does not monotonically improve with the injected field strength. Our numerical simulations suggest that the reduced phase model capture s the relevant dynamics well beyond the asymptotic regime in which it is derived.
