ABSTRACT:
An unimpeded optical path across a low-pressure supersonic stream of a high-power laser is achieved by rotating a window assembly at a predetermined constant speed. The centrifugal gasdynamic window assembly acts as a centrifugal compressor with no net radial flow. The no net radial flow condition is achieved by matching the compression ratio to the pressure difference between the flowing laser medium and ambient.
