Abstract

High-resolution laser spectroscopy of a Bose-Einstein condensate (BEC) was performed by using the ultranarrow magnetic quadrupole (6s2) 1S0 ↔ (6s6p)3P2 transition of ytterbium (Yb). The transition from the Dopplerbroadened spectrum of thermal atoms to the asymmetric spectrum, reflecting the inhomogeneous density distribution of a BEC in a harmonic trap, was observed. The role of the inter-atomic interaction was highlighted by performing spectroscopy of a BEC loaded in a one-dimensional (1D) optical lattice.
