Poincare maps are derived to describe antiphase spiking in class B multimode lasers. Analytical conditions are determined for phase synchronization and clustering of spikes associated with different longitudinal laser modes. Stabilization of splay states is proved in presence of small external signal.
We present a theoretical analysis of the dynamics of lasers with delayed optical feedback where the time delay
is periodically varied due to vibration of external mirror. Parameter regions have found of stable generation,
periodic and quasiperiodic oscillations in dependence on characteristics of vibration.
A direct comparison between continuous and discrete forms of
analysis of control and stability is investigated theoretically
and numerically. We demonstrate that the continuous method provides
a more energy-efficient means of controlling the switching of a
periodically-driven class-B laser between its stable and unstable
pulsing regimes. We provide insight into this result using the
close correspondence that exists between the problems of
energy-optimal control and the stability of a steady state.
Spontaneous pulsations of intensities, continuous change of instantaneous phase difference between counterrunning waves on (pi) transition from negative to positive tuning while their mean phase difference remains unaltered as well as jumps on 2(pi) mean phase differences were found in a four- frequency ring gas class-A laser with elliptically polarized eigenstates in the presence of linear coupling.
Theory is given for class B laser systems to find periodic unstable orbits due to large losses perturbations. The method allows to determine nonlocal organization of phase space, in particular, boundaries of attractive basins of attractors and stable manifold of repellers.
