Webmental results for the birefringence in silicon samples and a model reproducing the observed behavior. Based on our results we estimate the expected birefringence in the test-masses of ET. 1.1. Effect of birefringence in a Michelson-type interferometer In GW detectors, linearly polarized laser light is coupled into a resonant arm cavity formed by Webbirefringence increases up to 2o. In the rest of the sample where the mechanical stress is lower, the birefringence remains less than 1o as shown in Figure 5. We can conclude from above that, as long as the beam passes through the central area, inhomogeneous and stress induced birefringence is less than 1o for a sample thickness of 10cm.

http://cem01.ucsd.edu/courses/ece182/182-06_files/3birefringence.pdf WebBirefringence in an optical element leads to different optical path lengths, hence different wavefront aberrations, depending on the incident polarization state. Considering a single ray, the difference in the OPD of the two eigenpolarizations is referred to as the retardance, which is usually given the symbol δ.

WebBirefringence may be observed, however, when external forces are applied or when residual stresses are present (commonly the result of rapid cooling). The optical path difference δ (nm) associated with birefringence is linearly proportional to both the applied tensile or compressive stress, σ (105 Pa) and the
