Abstract: We present the results of an Adaptive Optics prototype system used to test the feasibility of active control for corrections of geometrical aberrations of gravitational wave interferometers input laser beam. It is shown that the efficiency of the system in correcting fluctuations extends up to 80 Hz unity gain frequency and that the upper limit of reintroduced noise is within gravitational wave interferometers requirements.
