Correlation analysis of spectral fluctuations in inhomogeneously broadenedspectra

It is shown that the lineshapes of inhomogeneously broadened spectra, due t o the statistical nature of their formation, exhibit spectral fluctuations. Formulas are obtained that allow one, based on correlation analysis of dif ferent realizations of the inhomogeneously broadened line, to reconstruct i ts homogeneous lineshape and to evaluate the number of centers involved in its formation. The magnitude of these spectral fluctuations is estimated an d it is shown that the proposed method can be efficiently used in practice. (C) 2001 Optical Society of America.
