The authors present new results on Te[sub 2] superfluorescence induced by short YAG-pumped dye laser pulses, analyzed at high resolution by comparison with CW laser induced fluorescence observed by Fourier transform spectroscopy. A complete identification of the transitions involved, based on intensity measurements and supported by calculated Franck-Condon factors, has been achieved. The cooperative emission in Te[sub 2] has been studied by time resolved spectroscopy as a function of density. With increasing density or temperature of the sample, the emission changes continuously from characteristic spontaneous emission to superfluorescence. Evolution of time characteristics of the signal with the number of partners are presented and discussed with respect to the predictions of current theories.
