Laser on mixtures of nitrogen with electronegative gases pumped by a transverse discharge from a generator with inductive energy storage: Theory and experiment
- Institute of High Current Electronics, Siberian Branch, Russian Academy of Sciences, Tomsk (Russian Federation)
Lasing and discharge characteristics of a nitrogen laser pumped by a transverse discharge from a generator with an inductive energy storage and a semiconductor current interrupter are investigated experimentally. A numerical model is proposed and the operation of a nitrogen-electronegative gas mixture laser is simulated. It is shown both theoretically and experimentally that admixtures of electronegative gases make it possible to control the laser pulse shape at the C{sup 3{Pi}}{sub u} - B{sup 3{Pi}}{sub g} transition of nitrogen. Laser pulses at a wavelength of 337.1 nm, consisting of two peaks, as well as rectangular pulses of duration 40-50 ns, are obtained in mixtures of nitrogen with NF{sub 3} and SF{sub 6} due to an increase in the electron attachment coefficient and an increase in the electric field. The output UV energy is {approx}25 mJ. (lasers)
