Abstract

We report an investigation of the transport properties in a pressurized gaseous medium by analyzing the temporal behavior of laser-induced gratings. Experiments were performed in various gas samples over a range of conditions. Acoustic damping rates were determined through model fits to the acquired signals. The results were compared with theoretical calculations from classical acoustic damping rates and previously measured results. The data indicates the importance of collisional energy transfer in determining acoustic damping.
