Characterization of semiconductor lasers often focuses on measurements of operating temperature of the device and output power of the coherent light produced based upon driving the device electrically or optically.  Given the low-dimensional nature of the quantum wells and the non-equilibrium conditions under which the devices are studied, they are of interest as a nonlinear system to physicists.  In order to obtain more information as feedback to the device designers and fabricators, both the spatial and temporal response of the output laser light from such devices are studied with a camera that is sensitive in the mid-IR.  The goal is to provide more detailed feedback to the design and production of semiconductor devices that can assess the quality of the beam produced and probe for additional effects in the devices from the driving, heating, and relaxation of the active region.  In addition, we are curious to find regions in phase space where the devices may demonstrate interesting non-equilibrium or nonlinear behavior, including low-dimensional chaos.  Chaos in such lasers could be used to securely encrypt information or communications between a sender and a receiver.  Both these goals and the current status of our efforts will be described and discussed.=0D=0A=
