Working on sagnac-interferometer, HWP(22.5) rotated laser light 45and tilt by mirror to define emergent orthogonal polarized component with frequency component is introduced.
I am working in Sagnac Interferometers. A vertically polarized liight fromaHe–Ne laser is converted into 45 deg linearly polarized light with the help of a half-wave plate (HWP1) oriented at 22.5 deg with respect to the vertical direction and is spatially filtered and collimated after passing through the spatial filter assembly(SF)and lens L.The beam splitter splits the collimated beam with equal intensity into two arms of the interferometer.The beam transmitted by beam splitter passes through atriangular Sagnac interferometer embedded intoa telescope assembly of lenses. The 45 deg polarized beam enters the polarization beam splitter and splits into two counter propagating orthogo nal polarization components in the triangular Sagnac geometry, and the light emits from the beam splitter as angular multi plexed orthogonally polarized components.The mirrors introduce the desired amount of tilt in the emergent orthogonally polarized components Ox and Oy,which can be representedas Ox(r)= exp(iα1r) and Oy(r)= exp(iα2r) ; where α1 andα2 are the frequency coefficients introduced to the orthogonal polarization components due to their off-axis locations in the front focal plane of lens,and r is the transverse spatial coordinate.I am working in Sagnac Interferometers.
