Webb20 nov. 2024 · Abstract: In this work, a polarization grating in Raman-Nath regime was fabricated by using a photoreactive polymer liquid crystal exhibiting biaxial optical anisotropy. And from the measured characteristics, it has been demonstrated that the flat incident angle dependences on diffraction efficiency and polarization ellipticity are … WebbWe propose a new atomic beamsplitter which uses Raman transitions via the far detuned excited state of an atom induced by four standing light waves. The splitting is not restricted to the Raman-Nath regime, and spontaneous emission is strongly suppressed. Therefore this scheme can be applied even for very slow atoms with strong transitions.
