Electric-discharge pulsed F{sub 2} + H{sub 2}(D{sub 2}) chain reaction HF/DF laser with a 4.2-L active volume
- FSUE Russian Centre of Science 'Applied Chemistry', St Petersburg (Russian Federation)
The properties of a pulsed chemical HF/DF laser with the 10 x 10.5 x 40-cm active volume and the 10-cm discharge gap are studied. Chain and nonchain chemical reactions were initiated by a barrier discharge in the active volume of the laser with the SF{sub 6} - H{sub 2}(D{sub 2}) and SF{sub 6} - F{sub 2} - O{sub 2} - H{sub 2}(D{sub 2}) mixtures, respectively. The discharge was stabilised by electrodes made of semiconductor ceramics. The maximum output energy of the 'nonchain'-mixture HF laser was E{sub max} = 15 J, the specific energy E/V = 3.6 J L{sup -1}, and the technical efficiency, calculated by the stored energy, was {eta}{sub t}= 4.3%. For the 'chain'-mixture HF laser, these parameters were E{sub max} = 130 J, E/V={sup 3}1{sup J} L{sup -1} and {eta}{sub t} = 37%. The parameters of the 'nonchain'- and 'chain'-mixture DF lasers were lower by {approx}35 % and {approx}50 %, respectively. (lasers)
