Abstract

Abstract: We report the first all-optical production of dual Bose–Einstein condensates (BECs) of paired 6 Li (fermion) and one spin state of 7 Li (boson) at the magnetic field where the s -wave interactions between fermions are resonant. Fermions are cooled efficiently by evaporative cooling and they serve as coolant for bosons. As a result, the dual condensates can be achieved by using a simple experimental apparatus and procedures, as in the case of the all-optical production of a single BEC. We show that the all-optical method enables us to realize variety of ultracold Bose–Fermi mixtures.
