Title: Subsonic flow aerodynamic window for high energy laser

Abstract: A subsonic flow aerodynamic window in a high energy gas laser, which seals off the laser optical cavity from the ambient gas, while minimizing the degradation of the laser output beam. Since the flow of the aerodynamic window is subsonic, gas consumption and degradation of the laser output beam are minimized.
