GROSS The Aerospace Corporation, El Segundo, California Continuous-wave (cw) chemically pumped lasing action from the chemical reaction F 4HF* H has been successfully demonstrated. To our knowledge, this is the first cw chemically pumped laser to be reported. Continuous radiation output in the 3-,u wavelength region a t power levels of -1 w have been observed for periods of time arbitrarily limited to -30sec. T h e technique employed involves a supersonic nitrogen jet, containing a dilute concentration of F atoms, flowing into a n ambient hydrogen atmosphere and past a n optical cavity. Diffusion of molecular hydrogen into the jet results in the generation of HF* which lases in the optical cavity. Calculations show that hydrogen is diffused throughout the jet before the j e t reaches the optical cavity. T h e dilute fluorine atom flow is obtained from the dissociation of SF, produced by heating a mixture of N, and SF, in a n arc heater to 2000°K. Gas pressures and residence times in the arc heater are adjusted to bring the SF, , N, mixture to chemical equilibrium. T h e gas
