An optically pumped ultraviolet laser on SO(B 3Σ−-X 3Σ−)

Lasing has been demonstrated in sulfur monoxide by pulsed optical pumping of transitions in the (0, 2) band of SO(B 3-SIGMA- - X 3-SIGMA-) at 256 nm. The SO is produced by 193 nm photolysis of sulfur dioxide. Stimulated emission is observed in the (0, 8), (0, 9), (0, 10), and (0, 11) bands between 300 and 350 nm.
