We measure the spontaneous emission lifetime of the D5/2 level of a single Ca+-ion by Pi-pulse excitation and quantum state detection. As the trapped ion is well localized we map the standing-wave cavity vacuum field.

Coherent coupling of a single Ca/sup +/ ion to a high finesse optical cavity field

Christoph Becher, Axel Kreuter, A.B. Mundt +6 more

Two experiments are performed to investigate the coherent interaction of a single Ca/sup +/ ion and a cavity field: first, Rabi oscillations are excited with short resonant laser pulses injected into the cavity, and second, change of the spontaneous emission rate are measured from the metastable D/sub 5/2 /level due to the cavity-enhanced vacuum field.

Spontaneous Emission Lifetime of a Single Trapped Ca+ Ion in a High Finesse Cavity

Axel Kreuter, Christoph Becher, Gavin P. T. Lancaster +7 more

We investigate the spontaneous emission lifetime of a single trapped (40)Ca+ ion placed at different positions in the vacuum standing wave inside a high finesse cavity which is stabilized to the atomic transition. The lifetime is measured by quantum state detection after pi-pulse excitation. The result for the natural lifetime of the D(5/2) metastable state of 1161(22) ms agrees, within 1 standard deviation, with the most precise published value. We observe a reduction of the spontaneous emission lifetime of approximately 15% in the node of the vacuum field.
