INITIAL PERFORMANCE OF A CW CHEMICAL LASER,
Abstract
Performance of a continuous HF chemical laser is presented. Population inversion was obtained by diffusion of H2 into a supersonic jet containing F atoms (H2 + F yields HF(v) + H, Delta H = -31.7 kcal/mole). A peak power of 630 W was obtained with an F atom flow rate of 0.040 mole/sec. The efficiency of conversion of chemical energy to laser energy was 12%. Performance of a corresponding DF laser is also given. Major laser output is from 2-1 and 1-0 transitions for both lasers. Radiation is at 2.6 to 2.9 microns and 3.6 to 4.0 microns for the HF and DF lasers, respectively. The ratio of DF to HF laser power is 0.7 under similar flow conditions. (Author)
