Abstract

The dc-Kerr constant was measured with high sen-sitivity in several gases, using a novel ellipsometer, which is based on a high-finesse Fabry-Pérot interferometer. An effective interaction length of 5.26 km was achieved by using a Fabry-Pérot interferometer with intracavity electrodes, yielding a single-pass sensitivity of ≈ 10 nanoradian. The dc-Kerr constants of CO2, N2, and O2 were determined with a high accuracy and with good agreement with previous measurements.
