Flow Visualization in a Chemical Laser Cavity by Pulsed Laser Holography.

Abstract

This report presents test results of flow visualization in a chemical laser cavity. Holograms were recorded of supersonic flow from a two-dimensional slit nozzle during test runs of HF or DF lasing. Laser cavity pressure was nominally 2 torr. Holographic reconstruction gave schlierens and shadowgraphs which were used to qualitatively define Mach numbers and nozzle exit plane boundary layers.
