Abstract
Variances and power spectra of the resonance fluorescence intensity induced by laser noise in two-level systems are studied theoretically. The effects of amplitude and phase noise fluctuations of a single-mode laser are investigated. Correlations of amplitude and phase fluctuations, as is relevant for excitation with diode lasers, are shown to lead to pronounced asymmetries in variance spectra.Keywords
