[Historical report created from submission:]

"We achieve degeneracy in a mixture of the two lowest hyperfine states of 6Li by direct evaporation in a CO2 laser trap, yielding the first all-optically produced degenerate Fermi gas. More than 105 atoms are confined at temperatures below 4 µK at full trap depth, where the Fermi temperature for each state is 8 µK. This degenerate two-component mixture is ideal for exploring mechanisms of superconductivity ranging from Cooper pairing to Bose condensation of strongly bound pairs."
