Paper 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.
