Use of very fast flow play a leading part in the development of high repetition rate high average power ultraviolet lasers. Moreover the very low temperature achievable by use of adiabatic expansion permits a strong increases of the laser or fluorescence optical power available for numerous systems. The aim of the paper is to present new results on ultraviolet and visible laser and fluorescent emissions obtained with the supersonic flow e-beam excitation and supersonic flow e-beam sustained or assisted discharge excitation I.M.F.M. device Ludwieg tube type blowdown. Particular emphasis will be made on the possibilities of the e-beam assisted discharge for the development of very fast flow high average power XeCl laser lambda 3080 a whom potential applications are numerous noticeably in the field of selective photochemistry, energetics and long-range communications.
