Abstract
A dye laser pumped Br2 B 3Π(0+u) → X 1Σ+g laser has been studied. Spectroscopic assignments have shown that lasing occurs from 10≤J′≤63 in 12≤v′≤17 using Rhodamine 590 dye. The output appeared limited to the 79–81 isotope of Br2. By utilizing stimulated emission as a monitor for laser excitation spectra, dramatic increases in the resolution were observed that exceeded the normal resolution of the dye laser. The Br2 laser operated at Br2 pressures of up to 60 Torr. A simple model to explain the characteristics of the Br2 laser is described.Keywords
