Abstract :
The first adaptive optics system for laser beam geometrical fluctuations correction, based on interferometric detection of aberrations, is presented. The bandwidth of the resulting feed-back is of several hundreds Hz and the residual fluctuations, measured on the error signal, are better than what can be obtained by typical Shack–Hartmann technique, encouraging for use in long baseline interferometers for GW detection.
