Abstract
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 ν. Th modulated fluorescence at 2ν, is shown to posses subnatural linewidth. The resolution of two lines lying within the natural linewidth of each other is explicitly considered.
