Abstract
A second-harmonic interferometer using pluses is presented, achieving a sensitivity of in measuring line-integrated dispersion between 1064 and . Using the same laser source, a third-harmonic interferometer is demonstrated for the first time to our knowledge, achieving a sensitivity of in measuring line-integrated dispersion between 1064 and . The prospect for the development and use of high-harmonic interferometry is discussed.
