摘要
The first adaptive optics system for laser beam geometrical fluctuations correction, based oil 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.
