On the basis of quantum microscopic approach we calculate dynamics of fluorescence of a cold atomic ensemble confined to special atomic trap and excited by pulse radiation. Using continuous wavelet transform with adaptive Morlet wavelet we analyze spectral composition of the fluorescence and its modification with time after the exciting pulse is switched off. Dependence of the spectrum on direction of fluorescence and its polarization is also analyzed.
