A second-harmonic interferometer based on a CW Nd:YAG laser is presented. The versatile device measures the line-integrated dispersion at the fundamental and second-harmonic wavelengths. A temporal resolution of 1.25 mu s with sensitivity of 1.3 mrad and a temporal resolution of 10 us with sensitivity of 0.3 mrad are demonstrated for a laser power of 0.6 W. For a laser power of only 150 mW a temporal resolution of 10 mu s with sensitivity of 1 mrad is reported. (C) 2007 Optical Society of America.
