High-pressure xenon laser at 1730 Å

Abstract
Experimental measurements are reported of optical gain due to stimulated transitions between the lowest-bound diatomic states of xenon (Xe) and the repulsive ground state. The optical gain was greatest at a wavelength of (1730 ± 10) Å, where the effective gain cross section is estimated to be 7 \times 10^{19} cm 2 .
