Abstract:
The generation and discharge are studied in a nonchain HF laser operating on mixtures of SF6 with hydrogen and hydrocarbons. The specific output energy of the laser is 8.8 J L-1 (73 J L-1 atm-1) and the total lasing efficiency is 5.5%. It is shown that the formation and maintaining of a volume discharge in self-sustained-discharge-pumped HF lasers with a large content of electronegative gases is caused by the accumulation of the volume discharge of negative ions in conducting regions.
