Abstract
Time-delayed measurement of naturally broadened transitions can lead to a narrowing of the linewidth. Moreover, under appropriate conditions, it may result in the appearance of a dip at the line center. An analysis of time-delayed measurement thus provides a theoretical basis for useful optical techniques yielding high spectral resolution. Such an analysis is presented in this work.Keywords
