Narrow-line magneto-optical trap for erbium

Atomic Physics 2014-05-09 v2 Quantum Gases

Abstract

We report on the experimental realization of a robust and efficient magneto-optical trap for erbium atoms, based on a narrow cooling transition at 583nm. We observe up to N=2×108N=2 \times 10^{8} atoms at a temperature of about T=15μKT=15 \mu K. This simple scheme provides better starting conditions for direct loading of dipole traps as compared to approaches based on the strong cooling transition alone, or on a combination of a strong and a narrow kHz transition. Our results on Er point to a general, simple and efficient approach to laser cool samples of other lanthanide atoms (Ho, Dy, and Tm) for the production of quantum-degenerate samples.
