PHOTOINITIATED F2 plus H2/D2 CHAIN-REACTION LASER WITH HIGH ELECTRICAL EFFICIENCY.

Article abstract of DOI:10.1063/1.323229

Performance characteristics are reported for a pulsed HF/DF laser initiated by photodissociation of F//2. Laser energy of 292 J is obtained from a 12. 8-1 active volume for 2. 5% HF content at 1-atm total pressure, giving 8. 1% chemical efficiency and 29% electrical efficiency. Thirty-three percent electrical efficiency is obtained with a 109-J laser energy. DF lasing produces 144 J with 14% electrical efficiency. Far-field measurements show a uniform beam profile with angular half-angle divergence of 5. 5 mrad, in good agreement with the value expected for multimode operation of the large-Fresnel-number stable resonator used.
