F. Brandi et al., MEASUREMENT OF THE PHASE ANISOTROPY OF VERY HIGH REFLECTIVITY INTERFERENTIAL MIRRORS, Applied physics. B, Lasers and optics, 65(3), 1997, pp. 351-355
We have measured the phase anisotropy of four very high reflectivity (
R > 0.999969) interferential mirrors for polarized light at strictly n
ormal incidence by studying the birefringence properties of a Fabry-Pe
rot cavity to which a Nd:YAG laser has been frequency locked. We found
phase anisotropies per reflection ranging from less than 2 x 10(-7) r
ad to 2 x 10(-6) rad.
