We demonstrate an atomic Faraday dichroic beam splitter suitable for spatially separating signal and idler fields from pump degenerate four-wave mixing in an atomic source. Color Separation Beam-splitters (Dichroic) The term dichroic refers to the splitting of light into two colors. When the transmittance for longer wavelength range is maximized, it is called "Long Wave Pass". After the dichroic beam splitter it is common to place a long pass filter to further enhance the separation between the strong excitation light (short wavelengths) and the weak fluorescence (longer wavelengths). A third version of the beam splitter is a dichroic mirrored prism assembly which uses dichroic optical coatings to divide an incoming light beam into a number of spectrally distinct output beams.
