Characterization of Spatiotemporal Structures in Lasers: A Progress Report
The introduction of the transverse dependence of the field in the analysis of the dynamics of lasers has already explained the presence of temporal instabilities at low values of the pump parameter for lasers operating in the good cavity limit [1,2]. However, the relevance of these studies does not expire with the detection of chaotic motion. The interplay of spatial and temporal degrees of freedom together with the highly nonlinear character of the Maxwell-Bloch equations of motion, make lasers with large transverse section good candidates for the characterization of complex spatiotemporal patterns and perhaps also of turbulent states. Moreover, the time scale of the laser dynamics offers a clear advantage over other fields of physics where spatiotemporal phenomena have been detected, from hydrodynamics to oscillating chemical reactions.
