Metal halide excimer lasers promise to be an efficient source of high power laser energy in the visible and near infrared. Based on extensive work on the HgBr laser we can expect that the nine lasers based on the group 2B metals (Zn, Cd, Hg) and the halides (Cℓ, Br, I) can each be tuned over a 1008 region. By using these lasers to pump hydrogen isotope Raman cells, a significant portion of the visible and near infrared can be accessed with practi-cal gas laser sources.
