Parametric investigations are described of a pulsed chemical hydrogen fluoride laser utilizing C/sub 3/H/sub 8/--SF/sub 6/, H/sub 2/--SF/sub 6/, and H/sub 2/--C/sub 3/H/sub 8/--SF/sub 6/ mixtures. An electrical efficiency of eta = 5% was obtained for multifrequency lasing, with an energy of 0.5 J and a peak intensity of 7.3 MW. Investigations were made of the temporal structure of pulses emitted by a laser with a nonselective resonator, of the mechanisms for the formation of spikes when lasing on individual vibrational--rotational transitions, and also of certain questions concerning the generation of short-duration (tau< or approx. =10 nsec) HF laser radiation pulses.
