Abstract
Progress is reported on an experiment to measure the Newtonian constnat of gravitation, G, with a suspended Fabry-Perot laser interferometer. With this technique, we measure the deflection of simple pendulums due to the gravitational attraction of tungsten masses. A result for G is expected with a relative uncertainty of 3 x 10-5.
