Permissible heating of a medium and specific ultraviolet output energy of an optically pumped J2 laser

An experimental investigation was made of an optically pumped ultraviolet J₂ laser and the permissible heating of a laser medium containing J₂ was analyzed. It was found that prolonged (1–2 msec) lasing of J₂ was possible and that the specific output energy was 100 J/g when the active medium had the composition CF₄ : J₂ and its density was 3 amagat.
