Time dependent linewidth: beat-note digital acquisition and numerical analysis

Not Accessible

Abstract

We revisit and improve the optical heterodyne technique for the measurement of the laser coherence, by digital acquisition of the beat-note and numerical analysis of the resulting signal, instead of using a traditionnal analog sweeping analyzer. The consequences are many.
