Harmonic interferometry in the visible and UV, based on second- and third-harmonic generation of a 25 ps mode-locked Nd:YAG laser.

A second-harmonic interferometer using 25 ps pluses is presented, achieving a sensitivity of 9x10(-10) m in measuring line-integrated dispersion between 1064 and 532 nm. Using the same laser source, a third-harmonic interferometer is demonstrated for the first time to our knowledge, achieving a sensitivity of 7x10(-9) m in measuring line-integrated dispersion between 1064 and 355 nm. The prospect for the development and use of high-harmonic interferometry is discussed.
