Abstract :
Submicrosecond pulses have been obtained from a photochemical H2-F2laser with a chemical efficiency of 0.5 percent. Energy densities of 6 J l-1were obtained from 60 torr (at 213 K) of a stoichiometric H2-F2mixture stabilized with 5 mole-percent O2. Laser output energy and the reciprocal of the pulsewidth were both proportional to the gas pressure. Actinometry showed that the laser energy output was 16.6 times the energy necessary to provide F atoms for initiation. Time-resolved spectra revealed excitation up to \\upsilon \´ = 6 .
