title: Heterodyne detection by using a diffraction-free beam: tilt and offset effects.
abstract: The advantage of using a diffraction-free light beam in heterodyne detection is investigated. Optimum values of tilt and offset of the incoming signal beam for attaining the maximum heterodyne mixing efficiency are identified.
