Resolved-sideband laser cooling in a Penning trap
- Abstract:
- We report the laser cooling of a single 40Caþ ion in a Penning trap to the motional ground state in one dimension. Cooling is performed in the strong binding limit on the 729-nm electric quadrupole S1=2↔D5=2 transition, broadened by a quench laser coupling the D5=2 and P3=2 levels. We find the final ground-state occupation to be 98(1)%. We measure the heating rate of the trap to be very low with _ n¯ ≈ 0.3ð2Þ s−1 for trap frequencies from 150–400 kHz, consistent with the large ion-electrode distance.
