Abstract
A holographic interferometer is described that is used in conjunction with a high-speed camera system (10,000 frames/sec) to record the temporal and spatial interactions of the laser gas medium and the resonator mode. In particular, a high-power CO2 electric discharge convectively cooled laser-gas medium was interferometrically analyzed before, during, and after laser power extraction such that the mode-medium interaction was observed.
