Transition from hexagons to optical turbulence

We characterize the different dynamical regimes and bifurcations in
the transition from a stationary hexagonal pattern to optical turbulence. In
order to characterize the bifurcations we perform linear stability analysis of
stationary hexagonal patterns and Floquet analysis of oscillating hexagons. The
interplay between space and time leads to a series of bifurcations showing
a mixture of spatial period multiplying and quasiperiodic scenarios.
