Optically pumped superfluorescence S2 molecular laser

Abstract
Superfluorescent laser emission has been achieved on the B 3Σ− u (v′=2) −X 3Σ− g (v ″=7–18) transitions of the S2 molecule by resonantoptical pumping at 337.1 nm with a nitrogen laser. It was observed on a series of ten near‐ultraviolet and visible lines from 370 to 490 nm with a mean induced gas near 0.05 cm−1. Discussion of pulsed laser operation including data on spectroscopic and dynamical processes is reported.
