Operation of a pulsed, multikilohertz-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. An average power of 12 W 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 a chain reaction in fluorine/hydrogen mixtures.
