Abstract
A cesium-based resonance fluorescence imaging monochromator (RFIM) is described. The spectral bandwidth of the detector was shown to be 0.4 GHz, the line width of one component of the hyperfine structure. The RFIM features sharp attenuation as close as 0.5 GHz from the center of a hyperfine component. The two-step excitation scheme gave a linear dependence on photon signal from the first ground state transition (852.12 nm), which was the wavelength detected in the RFIM. The spatial resolution of the detector was approximately 200 μm.
