For the first time superradiant emission from an electron-beam-excited dye vapor has been observed. Temporal and spectral characteristics are described that confirm the presence of stimulated emission. The wavelength integrated net gain of an optimized POPOP dye vapor--buffer gas mixture is found to be 0.17 cm/sup -1/ at 1 Torr and 4 atm argon pressures for an absorbed power input of 40 MW into an active volume of 10 cm/sup 3/. Under these conditions an estimate of the conversion efficiency from electronic energy to coherent light yields 5%. These results suggest that an efficient tunable electronically pumped dye vapor laser system is feasible.
