Abstract
We consider the suppression of the so-called "turbulent regimes" in optical systems with advection. It is well known that spatiotemporal systems submitted to advection can undergo a convective instability above a critical value of the drift parameter. The result is a hypersensivity to noise leading to spatiotemporal erratic regimes called noise sustained structures or "optical turbulence" [1]. This phenomenom appears with slight difference either in system with local saturation (e.g. liquid crystal with optical feedback) or with global saturation (e.g. actively mode-locked lasers).
