J. Poirson et al., MEASUREMENT OF WEAK INTRACAVITY ANISOTROP IES USING HIGH-FINESSE FABRY-PEROT CAVITIES, Annales de physique, 20(5-6), 1995, pp. 607-608
The dependence of the eigenstates of a high-finesse Fabry-Perot is sho
wn to provide a very sensitive method to characterize residual anisotr
opies of supemirrors at normal incidence and to measure weak intracavi
ty anisotropies. It leads to a sensitivity of. 10(-10) rad for phase r
etardance detection. A precise method for large finesse measurements i
s also demonstrated.
