Abstract

We confine 4\ifmmode×\else\texttimes\fi10⁸ fermionic ⁶Li atoms simultaneously with 9\ifmmode×\else\texttimes\fi10⁹ bosonic ⁷Li atoms in a magneto-optical trap based on an all-semiconductor laser system. We optimize the two-isotope sample for sympathetic evaporative cooling. This is an essential step towards the production of a quantum-degenerate gas of fermionic lithium atoms.
