We report heteronuclear photoassociation spectroscopy in a mixture of magneto-optically trapped 6Li and 7Li. The laser-induced decrease in the 7Li steady-state particle number, only appearing in the presence of 6Li, gives clear evidence of photoassociation to form 6Li7Li. Hyperfine resolved spectra of the vibrational level v=83 of the singlet state A1\ensuremathΣu+ have been taken up to intensities of 1000W/cm2. The absolute resonance frequencies and the rotational constant have been measured. Saturation of the photoassociation rate has been observed for two hyperfine transitions, which can be shown to be due to saturation of the rate coefficient near the unitarity limit. Saturation intensities on the order of 40W/cm2 can be determined.
