Abstract
Chemical laser action at atmospheric pressure has been observed from vibrational-rotational transitions of HF produced by multiple transverse spark discharges in C3H8 - He - SF6 mixtures. Lasing action was also observed when C4F8, C2F6 or CF4 replaced the SF6 and H2, CH4, C2H6 or C4H10 replaced C3H8. Peak powers in excess of 0.5 MW were obtained at low pressures; at atmospheric pressure, peak powers were of the order of 30 kW. The laser was, in some instances, super-radiant at pressures up to one atmosphere. P branch transitions from the v = 3, 2, 1 vibrational levels of HF were observed.
