Resolution beyond natural linewidth via flourescence in modulated beams Academic Article uri icon


  • A new method is proposed for obtaining spectral resolution beyond the natural linewidth using excitation by a laser beam whose intensity is weakly modulated in time at a low frequency . Th modulated fluorescence at 2, is shown to posses subnatural linewidth. The resolution of two lines lying within the natural linewidth of each other is explicitly considered. 1982.
