Pérez García, Victor M.. 

Local spatiotemporal chaos found in a dye laser has been experimentally studied and characterized as a weak turbulent system. Furthermore, a new model based on a discrete version of the Maxwell-Bloch equations seems to agree with the experimental results. The dynamical system’s nonstandard behavior in the form of a new type of frequency locking and the analysis of the decay of the energy fluctuations are herein described from both the theoretical and experimental points of view.
