We report the first all-optical production of dual Bose-Einstein condensates (BECs) of paired Li-6 (fermion) and one spin state of Li-7 (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.
