    Shaping Beam Profiles Using Plastic Optical Fiber Tapers with Application to Ice Sensors by Kostas Amoiropoulos, Georgia Kioselaki, Nikolaos Kourkoumelis, Aris Ikiades

    Published 2020-04-01
    “…Using either bulk or fiber optics the profile of laser beams can be altered from Gaussian to top-hat or hollow beams allowing enhanced performance in applications like laser cooling, optical trapping, and fiber sensing. Here, we report a method based on multimode Plastic Optical Fibers (POF) long-tapers, to tweak the beam profile from near Gaussian to a hollow beam, by generating surface irregularities on the conical sections of the taper with a heat-and-pull technique. …”

    Measuring the nuclear magnetic quadrupole moment of optically trapped ytterbium atoms in the metastable state by Ayaki Sunaga, Yuiki Takahashi, Amar Vutha, Yoshiro Takahashi

    Published 2024-01-01
    “…We propose a scheme to measure a nuclear magnetic quadrupole moment (MQM), a $\mathcal{CP}$ -violating electromagnetic moment that appears in the nuclear sector, using the long-lived $^3P_2$ metastable state in neutral ^173 Yb atoms. Laser-cooling and trapping techniques enable us to prepare ultracold ^173 Yb atoms in the $^3P_2$ state trapped in an optical lattice or an optical tweezer array, providing an ideal experimental platform with long spin coherence time. …”
