Dual-Platform Precision Measurement of the $3^{2} D_{5/2}$ to $4^{2} S_{1/2}$ $g$ -Factor Ratio in $^{40} Ca^{+}$

Brian J. McMahon, Vikram S. Sandhu, John M. Gray +3

We report precision measurements of the ratio of LandÃ© $g$ factors between the $3^{2} D_{5/2}$ and $4^{2} S_{1/2}$ states of a single trapped $^{40} Ca^{+}$ ion. The measurements ar…

Efficient Three-Dimensional Sub-Doppler Cooling of $^{40}$ Ca $^{+}$ in a Penning Trap

Brian J. McMahon, Brian C. Sawyer

We demonstrate efficient sub-Doppler laser cooling of the three eigenmodes of a $^{40}$ Ca $^{+}$ ion confined in a compact Penning trap operating with a magnetic field of 0.91 T. Usin…
