Abstract

The DF performance of the compact, repetitively pulsed HF/DF chemical laser, described at the last GCL, has been improved by using C₆D₁₂ instead of D₂ as deuterium donor. The output energy previously achieved with D₂ was low, less than 3 J per pulse compared to the HF energy of 10 J obtained with C₂H₆ as hydrogen donor for the same experimental conditions. Unfortunately, it was not possible to employ C₂D₆ because of the excessive cost of this deuterated compound. Therefore we made a search for a not too expensive deuterated hydrocarbon and we found that C₆D₁₂ could be an interesting product. We first tested C₆H₁₂ as a hydrogen donor instead of C₂H₆. Very good results were obtained on HF emission since the drop off in output energy was only about 5%. Consequently, C₆D₁₂ was ordered and tested. Output pulse energy up to 8 J was achieved at a charging voltage of 43 kV and a total pressure of 120 torr. In repetitive operation, typical average power of 450 W was achieved at a repetition rate of 65 Hz.
