High-energy lasing of XeBr in an electric discharge

Abstract

Using an electric discharge as the excitation source we have overcome the problem of Xe+2 absorption and have observed lasing at 282 nm in XeBr at the 60-mJ/pulse level. HBr is used as the halogen donor. Simultaneous laser oscillation at 291 nm in Br2 has also been observed. The present laser, however, has materials compatibility problems causing short static-fill lifetimes.
