Strong laser oscillation has been obtained on the electric-dipole-forbidden /sup 1/S/sub 0/-/sup 1/D/sub 2/ transition of atomic sulfur using 146-nm photodissociation of OCS. A photolytic mixture of OCS with N/sub 2/ and SF/sub 6/ produced optimum laser performance. Based on the laser output energy of 5 mJ at 772.5 nm, we infer that an energy density of 2.5 J/liter was stored in the laser transition immediately following photolysis. The one-half quenching time of S(/sup 1/S) atoms was approximately 1 ..mu..s for these conditions.
