Precise measurement of the difference of two decay rates and transient spectroscopy yielding subnatural linewidth Academic Article uri icon

abstract

  • The decay rates for the levels of a two-level system may be obtained by measuring the decay of the fluorescence intensity for the individual level, or may be inferred from the linewidth of the transition between them (which is equal to the sum). However, the difference of the decay rates can not be obtained accurately by subtracting one from the other, especially, for very similar decay rates. In this paper, we propose some techniques to measure the difference of the two rates directly. We also show that under certain conditions, subnatural linewidth spectroscopy could be obtained. 1989.
