Operating a near-concentric cavity at the last stable resonance
Chi Huan Nguyen, Adrian Nugraha Utama, Nick Lewty +1
Near-concentric optical cavities of spherical mirrors can provide technical advantages over the conventional near-planar cavities in applications requiring strong atom-light intera…
Single atoms coupled to a near-concentric cavity
Chi Huan Nguyen, Adrian Nugraha Utama, Nick Lewty +5
Concentric cavities can lead to strong photon-atom coupling without a need for high finesse or small physical-cavity volume. In a proof-of-principle experiment of this concept we d…
Experimental determination of the nuclear magnetic octupole moment of Ba ion
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We perform precision measurements on the 5D manifold hyperfine intervals of a single trapped ion, Ba. RF spectroscopy is used to measure the hyperfine intervals…
Sub-Doppler Cavity Cooling Beyond The Lamb-Dicke Limit
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We investigate the dynamics of cavity cooling of a single ion beyond the Lamb-Dicke regime and demonstrate a cooling limit of approximately 50% of the Doppler temperature using a h…
Minimization of Ion Micromotion in a Linear Paul Trap with a High Finesse Cavity
Boon Leng Chuah, Nicholas C. Lewty, Radu Cazan +1
We demonstrate minimization of ion micromotion in a linear Paul trap with the use of a high finesse cavity. The excess ion micromotion projected along the optical cavity axis or al…
Spectroscopy on a single trapped 137Ba+ ion for nuclear magnetic octupole moment determination
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We present precision measurements of the hyperfine intervals in the 5D3/2 manifold of a single trapped Barium ion, 137 Ba+ . Measurements of the hyperfine intervals are made betwee…
