Molecular Bose–Einstein condensation in a versatile low power crossed dipole trap

Abstract

We produce Bose-Einstein condensates of 6Li2 molecules in a low power (22 W) crossed optical dipole trap. Fermionic 6Li atoms are collected in a magneto-optical trap from a Zeeman slowed atomic beam and then loaded into the optical dipole trap where they are evaporatively cooled to quantum degeneracy. Our simplified system offers a high degree of flexibility in trapping geometry for studying ultracold Fermi and Bose gases.
