Abstract
One of the critical components of high-power lasers is the output coupling element. If output power exceeds a certain limit, it can become necessary to replace the solid window by another conception. In the experiment to be discussed in this contribution, an aerodynamic window has been chosen that uses a curved supersonic Jet to seal the low-pressure region of a simulated laser-cavity (100 mbar) against the ambient environment. A short description will be given of the principle, numerical calculation and design. Pressure measurements proving the fluidmechanical feasibility of the device will be presented. Its optical quality will be discussed along a series of shadowgraphs and interferograms.
