Isotope-selective photoionization for calcium ion trapping

Abstract:

We present studies of resonance-enhanced photoionization for isotope-selective loading of Ca+ into a Paul trap. The 4s2 1↔4s4p 1P1 transition of neutral calcium is driven by a 423 nm laser and the atoms are photoionized by a second laser at 389 nm. Isotope selectivity is achieved by using crossed atomic and laser beams to reduce the Doppler width significantly below the isotope shifts in the 423 nm transition. The loading rate of ions into the trap is studied under a range of experimental par...
