| مستخلص: |
A method for effectively removing background photons and improving the signal-to-background ratio in detection of fluorescence from a single cooled ion is described. In the method, an additional spatial filter placed at an off-focal position is used to remove scattered photons from trap-electrode surfaces. A signal-to-background ratio of more than 200 is obtained. By using this setup, a resolved carrier and motional sidebands on the 42S1/2–32D5/2 electric quadrupole transition in 40 Ca+ are observed.
