An one-dimensional optical lattice with rubidium atoms (85Rb) is formed inside a ring resonator with a finesse of 1.8\ifmmode×\else\texttimes\fi105 and a large mode volume of 2.6mm3. We typically trap several times 106 atoms at densities up to 1012cm^\ensuremath-3 and temperatures between 25 and 125\ensuremathμK. Despite of the narrow bandwidth (17.3 kHz) of the cavity, heating due to intracavity intensity fluctuations is kept at a low level, such that the time evolution of the temperature is determined by evaporative cooling.
