An one-dimensional optical lattice with rubidium atoms ({sup 85}Rb) is formed inside a ring resonator with a finesse of 1.8x10{sup 5} and a large mode volume of 2.6 mm{sup 3}. We typically trap several times 10{sup 6} atoms at densities up to 10{sup 12} cm{sup -3} and temperatures between 25 and 125 {mu}K. 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.
