Resolved-sideband laser cooling in a Penning trap

Abstract

We report the laser cooling of a single ${}^{40}{\text{Ca}}^{+}$ 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 $S_{1/2}\leftrightarrow D_{5/2}$ transition, broadened by a quench laser coupling the $D_{5/2}$ and $P_{3/2}$ levels. We find the final ground state occupation to be $98\pm 1\%$. We measure the heating rate of the trap to be very low with $\dot{\bar{n}}\approx 0.3\pm 0.2{\text{s}}^{-1}$ for trap frequencies from $150-400\text{kHz}$, consistent with the large ion-electrode distance.
