We report on the experimental realization of Bose–Einstein condensate (BEC) of 168Er atoms with tunable s-wave and dipolar interactions in a newly developed apparatus. Here, we describe an efcient method for trapping slow Er atoms in a narrow linewidth magneto-optical trap. After evaporative cooling in a crossed optical dipole trap, we achieve a spin-polarized condensate of > 2.5 × 104 atoms at the temperature of T ≃ 50 nK. The efcient preparation of ultracold erbium bosons ofers new possibilities for studying many-body physics with dipolar interactions.
