WebMar 30, 2024 · Here, the birefringence effect on the signal intensity and the spectral shape of a polarization-controlled coherent anti-Stokes Raman scattering (CARS) is theoretically described using a uniaxially symmetrical model system. Due to the complexity, the effect of phase delay in the incident lights is not considered but only that of the generated ... WebJan 18, 2013 · The birefringence intensity was found to vary as a function of the fiber orientation as related to crossed polarizers and as a function of the section thickness. In sections immersed in water for general observation of birefringence, CBs were observed in orientations nearly perpendicular to each other ( Fig. 1A ).
WebSep 7, 2024 · Probing vacuum structures deformed by high intense fields is of great interest in general. In the context of quantum electrodynamics (QED), the vacuum exposed by a linearly polarized high-intensity laser field is expected to show birefringence.
