Simultaneous Feedback Stabilization of Two Flute Modes of Similar Frequency

Abstract

A multimode feedback stabilization system which separates the modes by their spatial variation has been developed and used successfully in an experiment in which the m = 1 and m = 2 flute modes can exist simultaneously with almost the same frequency in the laboratory frame. The system allows separate control of each mode and, therefore, can be a useful… (More)
