This paper studies the optical quality such as the peak value (PV) of wavefront error, rms and strehl ratio (RS) of the free-vortex aerodynamic window(FADW) designed for the high energy lasers using the Hartmann-Shack sensing under different inlet total pressures experimentally. The results show that the effects on the output laser wavefront of the FADW are mainly the beam deflexion and the beam divergence, the other high-level wavefront errors are very low. And the FADW can meet our needs. The Hartmann-Shack sensing can be used to measure the 2-dimensional disturbed wavefront through the FADW dynamically and it can be used to launch and correct the high energy laser out of the FADW.
