A Pulsed, Multi-Kilohertz-Repetition-Rate, Supersonic HF Chemical Laser

D Chuchem, S Rosenwaks

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Operation of a pulsed, multi-kilohertz-repetition-rate, super­sonic HF chemical laser is described. Continuously flowing reactants are premixed and then expanded through a supersonic nozzle to the laser cavity where a pulsed electrical discharge initiates the chemi­cal reaction producing the lasing species. Average power of 12 watts has been obtained from a hydrogen/sulfur-hexafluoride/helium mixture. It is suggested that this apparatus can be used to overcome some of the inherent problems in achieving quasi-continuous laser operation based on chain reaction in fluorine/hydrogen mixtures.
