title: Optical fringe reduction technique for FM laser spectroscopy.
abstract: A simple and effective fringe reduction technique for FM 200 250 laser spectroscopy is discussed. A factor of 20 fringe reduction was observed in two-tone FM spectroscopy of water vapor. Theoretical simulations are compared to the exere perimental results.
